Physical Review B, 2017
We show that the peculiarities of the electron band structure strongly affect the spin-valve effect in heterostructures consisting of a superconductor (S) and two ferromagnetic layers ${\mathrm{F}}_{1}$ and ${\mathrm{F}}_{2}$. For the $\mathrm{S}/{\mathrm{F}}_{1}/{\mathrm{F}}_{2}$ systems the energy shift between the electron bands in the S and ...

Soliton dynamics in planar ferromagnets and anti-ferromagnets
Journal of Zhejiang University-SCIENCE A, 2003The aim of this paper is to present a rigorous mathematical proof of the dynamical laws for the topological solitons(magnetic vortices) in ferromagnets and anti-ferromagnets. It is achieved through the conservation laws for the topological vorticity and the weak convergence methods.

Ferromagnetic resonance in amorphous ferromagnet
Solid State Communications, 1984Abstract The peculiarities of the ferromagnetic resonance of an amorphous ferromagnet in which a certain number of atoms forms the two-level systems are studied. The logarithmic dependence upon the temperature and the applied magnetic field of the frequency shift of the ferromagnetic resonance is obtained.

Criteria for ferromagnetic–insulator–ferromagnetic tunneling
Journal of Magnetism and Magnetic Materials, 2002The Rowell criteria, commonly used to identify tunneling in magnetic tunnel junctions (MTJ), are scrutinized. While neither the exponential-thickness dependence of the conductivity nor fits of non-linear transport data are found to be reliable tunneling criteria, the temperature-dependent conductivity does remain a solid criterion.

Physical Review B, 1998
The tunneling conductance (TC) and magnetoresistance (TMR) are investigated for magnetic junctions consisting of two ferromagnetic electrodes separated by a ferromagnetic insulator (semiconductor). The investigations are based on the nearly-free-electron approximation.

Ferromagnetic resonance studies of multiphase ferromagnets
Journal of Magnetism and Magnetic Materials, 2000Abstract The theory of ferromagnetic resonance (FMR) and spin-wave resonance (SWR) is presented for the general case of multiphase ferromagnets, and applied to nanocrystalline materials, where nanometre size ferromagnetic crystals are embedded in an amorphous ferromagnetic phase which has a different magnetization. The possible existence of spin-wave

Ferromagnetism of UFe2 and Comparison with the Ferromagnetic Theories
Journal of Applied Physics, 1963The intermetallic compound UFe2 is ferromagnetic. A considerable number of magnetization isotherms have been obtained from 200°K down to 4.2°K with applied field up to 14 000 Oe. The Curie temperature has been determined to be 172°K and the Bohr magneton number 1.02 per UFe2 molecule.

A ferromagnetic resonance investigation of ferromagnetic coupling
Journal of Physics D: Applied Physics, 1997We present the ferromagnetic resonance (FMR) mode characteristics of two ferromagnetically coupled layers. Calculations are given for an applied DC magnetic field perpendicular to the film plane. The analysis predicts the number, positions, intensities and linewidths of the FMR peaks as functions of the coupling strength K.

Magnetotribology of ferromagnetic/ferromagnetic sliding couple
Wear, 2007Abstract Applied magnetic field around the rotating sliding ferromagnetic steel/steel modifies the friction and the wear behaviour of the contact. The friction tests where conducted in ambient air or in high vacuum chamber 10 −5 Pa. The applied normal loads are 0.1, 18.5 and 37 N. Without magnetic field, the contact is ductile steel against steel in
