Spectra and magnetic properties of large spins in external fields
(American Physical Society, 1999)
Spectra and magnetic properties of large spins J (e.g., spins possessed by ions or molecules), placed into a crystal electric field (CEF) of an arbitrary symmetry point group, are shown to change drastically when J changes ...
Angular-Dependence of the Critical Current in Layered Superconductors
(American Physical Society, 1992)
Angular dependence of metamagnetic transitions in HoNi2B2C
(American Physical Society, 1997)
Detailed measurements of M(2 K, H, theta) of HoNi2B2C, where theta is the angle that the applied field H makes with the [110] axis while remaining perpendicular to the crystallographic c axis, reveal three metamagnetic ...
Density of states and order parameter in dirty anisotropic superconductors
(American Physical Society, 1996)
We analyze in detail how the scattering by nonmagnetic impurities affects the shape and amplitude of the order parameter (OF) and the density of states in anisotropic superconductors in the framework of BCS theory. Special ...
Stripe Domain-Structures in a Thin Ferromagnetic Film
(American Physical Society, 1993)
We present a theory of the stripe domain structure in a thin ferromagnetic film with single-ion easy-axis magnetic anisotropy and long-range dipole interactions, for a wide range of temperatures and applied magnetic field. ...

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 ...
Phase-Diagram of Ultrathin Ferromagnetic-Films with Perpendicular Anisotropy
(American Physical Society, 1995)
Skyrmion in a real magnetic film
(American Physical Society, 1998)
Skyrmions are magnetic defects in ultrathin magnetic films, similar to the bubble domains in the thicker films. Even weak uniaxial anisotropy determines their radii unambiguously. We derive equations of slow dynamics for ...
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 ...
