The ferromagnetic layout in solid solutions of Lu2Fe17-xSix in homogeneity range (x ≤ 3.4) is accompanied by a giant volume magnetostriction, anisotropic with respect to principal axes of the hexagonal crystallographic structure. The volume effect in the ground state of Lu2Fe17 reaches 1.5% and decays monotonously to 0.9% for x = 3.4, together...
We have participated in study of electromagnetic properties of topic bulk high-Tc superconductors of the (Nd,Eu,Gd)BaCuO composition in which a tiny doping by Nb, Mo or Ti oxides leads to a substantial critical current density enhancement. In the composite doped by Nb2O5 the critical current density, Jc, reached the record values of 925 kA/cm2 (65...
We discovered that in thin amorphous tapes with an extremely low magnetostriction, annealed under mechanical pension, it is possible to reach enormously high level of non-diagonal magnetoimpedance with nearly linear dependence on the applied magnetic field [L. Kraus: J. Magn. Magn. Mater. 320 (2008) e746, doi:10.1016/j.jmmm.2008.04.043]. This...
The developed technique is based on the idea of optimization of earlier known magnetic hysteresis methods. Instead of collecting the usable information from measurement of the classical major hysteresis loop and keeping under surveillance dependence of its traditional parameters (coercive force, remanence, and saturation magnetization) on...
The spin and orbital magnetic moment and g-factor of FeSi Heusler alloys were determined experimentally by ferromagnetic resonance (FMR) and SQUID magnetometry and compared with calculations performed by fully relativistic density functional theory. The experimental data are in a good agreement with the theoretical ones. Further on, using FMR,...
