DYNAMICAL CROSSOVER IN THE NEUTRON SCATTERING OF ISOTROPIC FERROMAGNETS

Abstract
We study the shape crossover of the spin spin correlation function within mode coupling theory. At Tc the dipolar interaction is taken into account and the crossover in the transversal and longitudinal correlation function is studied. We also mention briefly the case T ≥ Tc for pure exchange interaction.
