A. Hucht et Kd. Usadel, CHARACTERIZATION OF THE REORIENTATION TRANSITION IN CLASSICAL HEISENBERG MODELS WITH DIPOLE INTERACTION, Journal of magnetism and magnetic materials, 156(1-3), 1996, pp. 423-424
In this paper the thermodynamics of thin ferromagnetic films are studi
ed in the framework of the classical Heisenberg model with uniaxial an
isotropy and long-range dipole interaction. The dependence of the orde
r of the reorientation transition in these systems on the number of la
yers and on the distribution of anisotropies is investigated using bot
h mean field theory and Monte-Carlo simulations.
