Моделирование гистерезиса спиновых системах

We present numerical studies of unidirectional anisotropy or exchange bias effect in coreshell complex two-dimensional nanoparticle. Within the frameworks of Ising and Heisenberg models the origin of exchange bias was revealed: it is an exchange interaction via interface of antiferromagnetic shell and ferromagnetic core of the nanoparticle. It was shown that Heisenberg model with Monte-Carlo step within small cone around the current spin position is more applicable for numerical simulation of spin dynamics in the complex core-shell nanoparticle.
