Multi-Step Magnetization Process of Gd-Co/Co/Cu/Co Thermo-Sensitive Spin Valves

Magnetic and magnetoresistive properties of the Gd-Co/Co/Cu/Co magnetic type multilayered sensitive spin valve were studied as a function of temperature. It is shown that the appearance of a non-collinear magnetic structure significantly affects the shape of the magnetoresistive hysteresis loop. The characteristic values of the critical field related to the appearance of non-collinear structure depend on the temperature of the spin valve. The obtained results can serve as a basis for the improvements of functional properties and expanding the application areas of magnetic multilayered sensitive elements of the spin valve type; for example, for precise determination of the position of the object.This work was in part supported by RFBR grant 17-02-00236-a of Russian Federation and by the ACTIMAT ELKARTEK KK-2016/00097 grant of the Basque Country Government

Euskal toponimia, baserrien izenak eta deituren ondarea, Gizarte-Zientziak ikasteko abiapuntu. Bigarren hezkuntzarako proposamena

The paper presents a proposal for Social Sciences teaching-learning in Secondary Education. It starts with current Basque surnames that come from the name of the "baserriak", the traditional homes of the Basque provinces of Bizkaia, Gipuzkoa, north Alava and Navarra and the French Basque Country. In times difficult to be determined, the communal lands began to be privatized, adopting the form of circular plots. The documentation written in romance language calls these plots "sel", a word of pre-Roman origin that was also kept in Basque language. Sels gave birth to a number of place names some of which were used to name the house built on these particular lands. These farm names in many cases also provided the surnames for individual Basque families living there. Our proposal identifies existing seles, displays a number of historical and geographical online tools and offers students a number of activities for building a socio-historical knowledge well related to their own reality.; Cet travail présente une proposition de l’enseignement-apprentissage des sciences sociales pour l’enseignement secondaire, en prenant comme point de départ les noms basques qui ont pour origine le nom de la ferme, qui est la maison traditionnelle des provinces de Biscaye, Guipúzcoa, au nord d’Alava et Navarre et le Pays Basque Français .En temps difficiles de déterminer les terres communales ont commencé à être privatisées, sous forme de parcelles circulaires. La documentation écrié en lange espagnole appel ces parcelles "sel", un mot d’origine préromaine. En basque ont abouti à un certain nombre de noms de lieux, dont certains ont servi à appeler la maison que a été construite sur eux. Cela a servi comme un nom patronymique aux habitants de ces fermes. Notre proposition offre un certain nombre de outils historiques et géographiques abordables en ligne et quelques suggestions d’activités pour les étudiants, à construire une connaissance socio-historique lié à leur propre réalité.; El artículo presenta una propuesta de enseñanza-aprendizaje de las Ciencias Sociales para Educación Secundaria, tomando como punto de partida los apellidos vascos que tienen su origen en el nombre del caserío, es decir, la casa tradicional de las provincias de Bizkaia, Gipuzkoa, norte de Álava y de Navarra y el País Vasco Francés. En época difícil de determinar los terrenos comunales comenzaron a privatizarse, adoptando la forma de parcelas circulares. La documentación en romance los denomina seles, un vocablo de origen prerromano y en euskara han dado lugar a una serie de topónimos, algunos de los cuales pasaron a nombrar al caserío que se construyó en los mismos. Y los que habitaron en dichos caseríos lo adoptaron como patronímico. En la propuesta se ofrecen una serie de herramientas histórico-geográficas asequibles en Internet y se sugieren actividades para que el alumnado construya un conocimiento socio histórico conectado con su propia realidad

El aprendizaje-servicio: una herramienta en la formación del profesorado en clave intercultural. Construyendo puentes entre Ecuador y Euskadi

With the aim of analysing the benefits of the service-learning methodology in the acquisition of intercultural competences of teacher training students and pre-service teachers, an experience was carried out during the 2016-2017 academic year. A total of 54 students from the Faculty of Education and Sport of the University of the Basque Country in Vitoria-Gasteiz took part. The results showed that pre-service teachers demanded to experience a more active training model that was truly committed to society and to themselves and through which they could not only develop their intercultural competences, but they could also grow as fair, critical people, committed to the community, regardless of the context of the learning experience. The paper concludes that the use of active methodologies such as service-learning has a significant pedagogical, social, democratic and formative value for students as it impacts on their personal and professional development, fostering the development of their intercultural competence and increasing their level of community engagement, which are all essential values.Teniendo como objetivo responder a la pregunta: ¿cuál es la contribución que la implementación de la metodología aprendizaje-servicio tiene en la adquisición de competencias interculturales de nuestro alumnado de magisterio y del futuro profesorado?, esta experiencia, se desarrolló durante el curso 2016-2017 y participaron un total de 54 alumnos de la Facultad de Educación y Deporte de la Universidad del País Vasco de Vitoria-Gasteiz. Como resultado, se evidencia que los futuros docentes demandaban experimentar un modelo de formación más activa y verdaderamente comprometida con la sociedad y con ellos mismos en la que además de desarrollar sus competencias interculturales, se pudieran desarrollar también como personas justas, críticas comprometidas con la comunidad, indistintamente del contexto de su localización. Se concluye que la utilización de este tipo de metodologías activas como el aprendizaje-servicio poseen un gran valor pedagógico, social, democrático y formativo del alumnado porque incide en sus aspectos personales y profesionales, favoreciendo el desarrollo de su competencia intercultural y aumentando su nivel de compromiso comunitario, valores estos fundamentales

Optimization and Prediction Techniques for Self-Healing and Self-Learning Applications in a Trustworthy Cloud Continuum

The current IT market is more and more dominated by the “cloud continuum”. In the “traditional” cloud, computing resources are typically homogeneous in order to facilitate economies of scale. In contrast, in edge computing, computational resources are widely diverse, commonly with scarce capacities and must be managed very efficiently due to battery constraints or other limitations. A combination of resources and services at the edge (edge computing), in the core (cloud computing), and along the data path (fog computing) is needed through a trusted cloud continuum. This requires novel solutions for the creation, optimization, management, and automatic operation of such infrastructure through new approaches such as infrastructure as code (IaC). In this paper, we analyze how artificial intelligence (AI)-based techniques and tools can enhance the operation of complex applications to support the broad and multi-stage heterogeneity of the infrastructural layer in the “computing continuum” through the enhancement of IaC optimization, IaC self-learning, and IaC self-healing. To this extent, the presented work proposes a set of tools, methods, and techniques for applications’ operators to seamlessly select, combine, configure, and adapt computation resources all along the data path and support the complete service lifecycle covering: (1) optimized distributed application deployment over heterogeneous computing resources; (2) monitoring of execution platforms in real time including continuous control and trust of the infrastructural services; (3) application deployment and adaptation while optimizing the execution; and (4) application self-recovery to avoid compromising situations that may lead to an unexpected failure.This research was funded by the European project PIACERE (Horizon 2020 research and innovation Program, under grant agreement no 101000162)

Amorphous FeCoCrSiB Ribbons with Tailored Anisotropy for the Development of Magnetic Elements for High Frequency Applications

The ferromagnetic resonance (FMR) in the frequency range of 0.5 to 12.5 GHz has been investigated as a function of external magnetic field for rapidly quenched Fe3Co67Cr3Si15B12 amorphous ribbons with different features of the effective magnetic anisotropy. Three states of the ribbons were considered: as-quenched without any treatment; after relaxation annealing without stress at the temperature of 350 °C during 1 h; and after annealing under specific stress of 230 MPa at the temperature of 350 °C during 1 h. For FMR measurements, we adapted a technique previously proposed and tested for the case of microwires. Here, amorphous ribbons were studied using the sample holder based on a commercial SMA connector. On the basis of the measurements of the reflection coefficient S11, the total impedance including its real and imaginary components was determined to be in the frequency range of 0.5 to 12.5 GHz. In order to confirm the validity of the proposed technique, FMR was also measured by the certified cavity perturbation technique using a commercial Bruker spectrometer operating at X-band frequency of 9.39 GHz. As part of the characterization of the ribbons used for microwave measurements, comparative analysis was performed of X-ray diffraction, optical microscopy, transmission electron microscopy, inductive magnetic hysteresis loops, vibrating sample magnetometry, magneto-optical Kerr effect (including magnetic domains) and magnetoimpedance data for of all samples.The research funding from the Ministry of Science and Higher Education of the Russian Federation (Ural Federal University Program of Development within the Priority-2030 Program) is gratefully acknowledged.

Modifying the magnetic response of magnetotactic bacteria: incorporation of Gd and Tb ions into the magnetosome structure

Magnetotactic bacteria Magnetospirillum gryphiswaldense MSR-1 biosynthesise chains of cube-octahedral magnetosomes, which are 40 nm magnetite high quality (Fe3O4) nanoparticles. The magnetic properties of these crystalline magnetite nanoparticles, which can be modified by the addition of other elements into the magnetosome structure (doping), are of prime interest in a plethora of applications, those related to cancer therapy being some of the most promising ones. Although previous studies have focused on transition metal elements, rare earth (RE) elements are very interesting as doping agents, both from a fundamental point of view (e.g. significant differences in ionic sizes) and for the potential applications, especially in biomedicine (e.g. magnetic resonance imaging and luminescence). In this work, we have investigated the impact of Gd and Tb on the magnetic properties of magnetosomes by using different complementary techniques. X-ray diffraction, transmission electron microscopy, and X-ray absorption near edge spectroscopy analyses have revealed that a small amount of RE ions, similar to 3-4%, incorporate into the Fe3O4 structure as Gd3+ and Tb3+ ions. The experimental magnetic characterisation has shown a clear Verwey transition for the RE-doped bacteria, located at T similar to 100 K, which is slightly below the one corresponding to the undoped ones (106 K). However, we report a decrease in the coercivity and remanence of the RE-doped bacteria. Simulations based on the Stoner-Wohlfarth model have allowed us to associate these changes in the magnetic response with a reduction of the magnetocrystalline (K-C) and, especially, the uniaxial (K-uni) anisotropies below the Verwey transition. In this way, K-uni reaches a value of 23 and 26 kJ m(-3) for the Gd- and Tb-doped bacteria, respectively, whilst a value of 37 kJ m(-3) is obtained for the undoped bacteria.This work was supported in part by the Spanish MCIN/AEI under Projects MAT2017-83631-C3-R and PID2020-115704RB-C33.

Elucidating the role of shape anisotropy infaceted magnetic nanoparticles using biogenicmagnetosomes as a model

Shape anisotropy is of primary importance to understand the magnetic behavior of nanoparticles, but a rigorous analysis in polyhedral morphologies is missing. In this work, a model based on finite element techniques has been developed to calculate the shape anisotropy energy landscape for cubic, octahedral, and truncated-octahedral morphologies. In all cases, a cubic shape anisotropy is found that evolves to quasi-uniaxial anisotropy when the nanoparticle is elongated >= 2%. This model is tested on magnetosomes, similar to 45 nm truncated octahedral magnetite nanoparticles forming a chain inside Magnetospirillum gryphiswaldense MSR-1 bacteria. This chain presents a slightly bent helical configuration due to a 20 degrees tilting of the magnetic moment of each magnetosome out of chain axis. Electron cryotomography images reveal that these magnetosomes are not ideal truncated-octahedrons but present approximate to 7.5% extrusion of one of the {001} square faces and approximate to 10% extrusion of an adjacent {111} hexagonal face. Our model shows that this deformation gives rise to a quasi-uniaxial shape anisotropy, a result of the combination of a uniaxial (Ksh-u = 7 kJm(-3)) and a cubic (Ksh-c = 1.5 kJ m(-3)) contribution, which is responsible for the 20 degrees tilting of the magnetic moment. Finally, our results have allowed us to accurately reproduce, within the framework of the Landau-Lifshitz-Gilbert model, the experimental AC loops measured for these magnetotactic bacteria.Spanish Government is acknowledged for funding under the project number MAT2017-83631-C3.

Mechanical, Electrical and Magnetic Properties of Ferrogels with Embedded Iron Oxide Nanoparticles Obtained by Laser Target Evaporation: Focus on Multifunctional Biosensor Applications

Hydrogels are biomimetic materials widely used in the area of biomedical engineering and biosensing. Ferrogels (FG) are magnetic composites capable of functioning as magnetic field sensitive transformers and field assisted drug deliverers. FG can be prepared by incorporating magnetic nanoparticles (MNPs) into chemically crosslinked hydrogels. The properties of biomimetic ferrogels for multifunctional biosensor applications can be set up by synthesis. The properties of these biomimetic ferrogels can be thoroughly controlled in a physical experiment environment which is much less demanding than biotests. Two series of ferrogels (soft and dense) based on polyacrylamide (PAAm) with different chemical network densities were synthesized by free-radical polymerization in aqueous solution with N, N'-methylene-diacrylamide as a cross-linker and maghemite Fe2O3 MNPs fabricated by laser target evaporation as a filler. Their mechanical, electrical and magnetic properties were comparatively analyzed. We developed a giant magnetoimpedance (MI) sensor prototype with multilayered FeNi-based sensitive elements deposited onto glass or polymer substrates adapted for FG studies. The MI measurements in the initial state and in the presence of FG with different concentrations of MNPs at a frequency range of 1-300 MHz allowed a precise characterization of the stray fields of the MNPs present in the FG. We proposed an electrodynamic model to describe the MI in multilayered film with a FG layer based on the solution of linearized Maxwell equations for the electromagnetic fields coupled with the Landau-Lifshitz equation for the magnetization dynamics.This work was supported in part within the framework of the state task of the Ministry of Education and Science of Russia 3.6121.2017/8.9; RFBR grants 16-08-00609-a, 18-08-00178, and by the ACTIMAT ELKARTEK grant of the Basque Country Government.
