Critical dynamics of dipolar ferromagnets

Abstract

The dynamical scaling functions for ferromagnets with dipolar interactions are computed by mode coupling theory above the critical temperature Tc. On the basis of this theory we explain apparently conflicting features of neutron scattering experiments on EuO, EuS and Fe. The position of the crossover from isotropic to dipolar critical dynamics is determined and further experiments are proposed.
