  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.
