The critical dynamics of the models of iron-vanadium magnetic superlattice

Abstract

We report the results of a numerical investigation of static and dynamic critical behavior of the anisotropic easy-plane Heisenberg model which is used as a model for iron-vanadium magnetic superlattices. Models of iron-vanadium magnetic superlattice investigated with different values of intralayer and interlayer exchange interactions ratio. Numerical experiment technique, based on the dynamic finite-size scaling theory. Basic features of the time evolution of dynamic parameters for the researched systems are studied. The effect of interlayer exchange interaction value on a character of the critical dynamics is determined. It is confirmed the possibility of application of the Hamiltonian with strong easy-plane anisotropy for investigation both static and dynamic critical behavior of complex planar magnetic models.
