Ferromagnetic microswimmer

Physical Review E, 2009
The self-propelling motion of the flexible ferromagnetic swimmer is described. Necessary symmetry breaking is achieved by the buckling instability at field inversion. The characteristics of self-propulsion are in good agreement with the numerical calculations of the Floquet multipliers for the ferromagnetic filament under the action of ac magnetic ...

Multi-state magnetoresistance in ferromagnet/organic-ferromagnet/ferromagnet junctions

Applied Physics Letters, 2014
Spin-dependent transport through a ferromagnetic metal/organic-ferromagnet/ferromagnet metal junction is investigated theoretically. It is demonstrated that the current through the device strongly depends on the alignment of the magnetization orientations of the electrodes and interlayer.

Tunneling Magnetoresistance in Ferromagnet/Insulator/Ferromagnet Junctions

International Journal of Modern Physics B, 1997
A δ-type potential with complex prefactor is modeled on the tunneling barrier of a thin insulator (I) film separating two ferromagnetic (FM) films. By matching value and slope of wave functions across the tunneling barrier of a FM/I/FM junction, we obtain a general expression for tunneling conductance as a function of relative orientation θ between ...

Conductance spectra of asymmetric ferromagnet/ferromagnet/ferromagnet junctions

Journal of Magnetism and Magnetic Materials, 2017
Abstract A theory of tunneling spectroscopy of ferromagnet/ferromagnet/ferromagnet junctions was studied. We applied a delta-functional approximation for the interface scattering properties under a one-dimensional system of a free electron approach.

Nuclear Ferromagnetism and Antiferromagnetism

Physica B+C, 1977
Abstract This article, written for the lay reader, describes some studies, initiated in the author's laboratory in the late 1960s and pursued there for more than 15 years. The interested reader can find a full technical description in the book Nuclear Magnetism. Order and Disorder by A. Abragam and M. Goldman. The present account is an abridged version

Ferromagnetic resonance in amorphous ferromagnet

Solid State Communications, 1984
Abstract 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.

Ferromagnetism

2022
Abstract Magnetism and order parameters are discussed in both mean field theory and exact treatments. An example of stochastic dynamics for the Ising model is given. The Curie–Weiss model is defined as a system in which mean field theory is exact.

Ferromagnetism

1997
Abstract The termferromagnetismis used to characterize strongly magnetic behavior, such as the strong attraction of a material to a permanent magnet. The origin of this strong magnetism is the presence of a spontaneous magnetization produced by a parallel alignment of spins.
