摘要：
The magnetic properties of thin ferromagnetic films are studied using a mean-field model. The thickness dependent film Curie temperature T(c)(d) is calculated for different surface magnetic moments mu(s) as well as for different lattice types and -faces. For an enhanced mu(s) the bulk Curie temperature T(c)(infinity) can be reached within a few layers or may even be exceeded. The layer dependent magnetization curves m(i)(T) are calculated for a few systems, assuming Ising as well as Heisenberg type spins. Thermal fluctuations are partly taken into account by an improved mean field theory. The main features of our results seem to be presented in the presence of fluctuations.
