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

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 are 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 the character of critical dynamics is determined. It confirmed the possibility of application of the Hamiltonian with strong easy-plane anisotropy for investigation of both static and dynamic critical behavior of complex planar magnetic models.
