Abstract
The dependence of the spin reorientation transition in ultrathin ferromagne tic films on external magnetic fields is studied. For different orientation s of the applied field with respect to the film, phase diagrams are calcula ted within a mean-field theory for the classical Heisenberg model. In parti cular we find that the spin reorientation transition present in this model is not suppressed completely by an applied field, as the magnetization comp onent perpendicular to the field may show spontaneous order in a certain te mperature interval.
