Theory of the hysteresis loop in ferromagnets
(American Physical Society, 1999)
We consider three mechanisms of hysteresis phenomena in alternating magnetic field: the domain-wall motion in a random medium, the nucleation, and the retardation of magnetization due to slow (critical) fluctuations. We ...
Long-wavelength anomalous diffusion mode in the two-dimensional XY dipole magnet
(American Physical Society, 1997)
In a two-dimensional XY ferromagnet the dipole force induces a strong interaction between spin waves in the long-wavelength limit. The major effect of this interaction is the transformation of a propagating spin wave into ...
