Angular variation of the magnetoresistance of the superconducting ferromagnet UCoGe
We report a magnetoresistance study of the superconducting ferromagnet UCoGe.
The data, taken on single-crystalline samples, show a pronounced structure at
~T for a field applied along the ordered moment . Angle
dependent measurements reveal this field-induced phenomenon has an uniaxial
anisotropy. Magnetoresistance measurements under pressure show a rapid increase
of to 12.8~T at 1.0~GPa. We discuss in terms of a field induced
polarization change. Upper critical field measurements corroborate the unusual
S-shaped -curve for a field along the -axis of the orthorhombic
unit cell.Comment: 6 pages, 5 figures; accepted for publication in Phys. Rev.
High-pressure study of the basal-plane anisotropy of the upper critical field of the topological superconductor SrxBi2Se3
We report a high-pressure transport study of the upper-critical field,
, of the topological superconductor SrBiSe ( K). was measured for magnetic fields directed along two
orthogonal directions, and , in the trigonal basal plane. While
superconductivity is rapidly suppressed at the critical pressure
GPa, the pronounced two-fold basal-plane anisotropy at K, recently reported at ambient pressure (Pan et al., 2016), is
reinforced and attains a value of at the highest pressure (2.2 GPa).
The data reveal that the unconventional superconducting state with broken
rotational symmetry is robust under pressure
Superconductivity and magnetic order in the non-centrosymmetric Half Heusler compound ErPdBi
We report superconductivity at K and magnetic order at K in the semi-metallic noncentrosymmetric Half Heusler compound ErPdBi.
The upper critical field, , has an unusual quasi-linear temperature
variation and reaches a value of 1.6 T for . Magnetic order is
found below and is suppressed at T for . Since , the interaction of superconductivity and magnetism
is expected to give rise to a complex ground state. Moreover, electronic
structure calculations show ErPdBi has a topologically nontrivial band
inversion and thus may serve as a new platform to study the interplay of
topological states, superconductivity and magnetic order.Comment: 6 pages, 5 figures; accepted for publication in Europhysics Letter
ONTOLOGICAL AND SOCIO-CULTURAL FOUNDATIONS OF THE INTER-GENERATED DISCOURSE IN THE MODERN INFORMATION SOCIETY
Purpose of the study: The article is devoted to understanding the problems of intergenerational discourse and its transformation in ontological and sociocultural reality. The paper substantiates the need to maintain the mechanism of accumulation and reproduction of the experience of ancestors. It is shown that the violation of the transfer of knowledge and traditions leads to the distortion or disappearance of universal cultural codes.
Methodology: In this article, cultural, demographic, and psychological approaches are used to study the ontological and sociocultural foundations of intergenerational discourse. It is necessary to show the influence of historical and socio-cultural transformations on the characteristics of interaction between generations, to determine the form of transfer and assimilation of experience within the family, to demonstrate the socially significant consequences of the demographic revolution in the modern information society.
Main Findings: Having outlined only a few reasons for the intergenerational discourse in the field of translation of sociocultural experience, it can be noted that their combination forms the layer of human life in which historically determined values and ideals of human society are realized, methods of accumulation and transfer of experience that are unique for each historical era, new methods communications.
Applications of this study: Research results can be applied in the course of social psychology (today, young people are literally imposed a radical cultural gap with previous generations), social philosophy, cultural studies (the form of transfer of experience within the family) and even demography (large-scale changes in human society, with the destruction of human social instincts).
Novelty/Originality of this study: As the initial task of the study, it is supposed to identify historical and sociocultural changes in the field of translation and appropriation of experience, to conduct a cultural analysis that gives a clear idea of the evolution of the methods of interaction between generations. An interdisciplinary approach involves a wider coverage of existing concepts and shows that the patterns of development of human society cannot be reduced only to biological, economic or socio-cultural patterns
