Nonequilibrium Multicritical Behaviour in Anisotropic Heisenberg Ferromagnet driven by Oscillating Magnetic
, 2005
"... The Heisenberg ferromagnet (uniaxially anisotropic along zdirection), in the presence of time dependent (but uniform over space) magnetic field, is studied by Monte Carlo simulation. The time dependent magnetic field was taken as elliptically polarised in such a way that the resulting field vector ..."

Abstract Explicit solutions of the chain equations describing discrete transformations of the LandauLifshitz equation are found in the most economical way. This chain can be considered as a generalization of the Toda chain (the case of a rational spectral parameter) to the case of an elliptic curve. We show that the process of deriving multisoliton solutions of the LandauLifshitz equation in an explicit form with help of these results becomes relatively straightforward.

Topological Excitations on a Classical 2D EasyAxis Heisenberg Model
