Structural and Magnetic Properties of Nano-Sized NiZn Ferrites

Structural and magnetic properties (such as e.g. size of crystallites, lattice parameter, magnetic susceptibility, Curie temperature, etc.) of nano-sized $Ni_{0.33}Zn_{0.67}Fe_{2}O_{4}$ ferrites have been studied. The obtained results demonstrated that the sintering temperature is an efficient and simple tool for controlling the size of crystallite particles, thus affecting the resulting magnetic properties. Straightforward relationship between the sintering temperature and the size of crystallites was found, meanwhile no other crystalline phases than the spinel one were detected by two independent analytic methods

LSMO Films with Increased Temperature of MI Transition

Epitaxial $La_{0.67}Sr_{0.33}MnO_{3}$ thin films with a significant increased temperature of metal-insulator transition (~450 K) are prepared on single crystal MgO (001) substrates using different deposition techniques - a dc magnetron sputtering or a pulsed laser deposition. The crystalline perfection of the films is characterized by X-ray diffraction technique (rocking curve measurements and reciprocal space maps). As a consequence of different methods of the film preparation we show various types of the LSMO crystal structure. Our results indicate that all the LSMO layers grown on the MgO substrate with a lattice misfit of about 8% are relaxed

Tartrate-Based Electrolyte for Electrodeposition of Fe–Sn Alloys

Magnetic properties of the sustainable Fe−Sn alloys are already known. However, there is lack of information in the field of Fe−Sn electrodeposition. In the present study, a novel Fe(III)−Sn(II) electrolyte with tartaric acid as a single complexing agent is introduced. The influence of the pH and the current density on the structural properties of the Fe−Sn deposit was studied. The stability of the electrolytes as a main attribute of sustainability was tested. The ferromagnetic phases Fe5Sn3 and Fe3Sn were electrodeposited for the first time, and it was found that the mechanism of the Fe−Sn deposition changes from normal to anomalous at a pH value 3.0 and a current density of approximately 30 mA/cm2. A possible reason for the anomalous deposition of Fe−Sn is the formation of Fe-hydroxides on the cathode surface. Two electrolyte stability windows exist: The first stability window is around a pH value of 1.8 where bimetallic Fe−Sn tartrate complexes were formed, and second one is around a pH value of 3.5 where most of the Sn ions were present in the form of [Sn(tart)2]2− and Fe in the form of [Fe(tart)]+ complexes
