摘要：

The influence of uniaxial anisotropy and the dipole interaction on the direction of the magnetization of ultrathin ferromagnetic films in the ground state is studied. The ground-state energy can be expressed in terms of anisotropy constants which are calculated in detail as a function of the system parameters and the film thickness. In particular noncollinear spin arrangements are taken into account. Conditions for the appearance of a spin reorientation transition are given and analytic results for the width of the canted phase and its shift in applied magnetic fields associated with this transition are derived.
