摘要：

We show that the two-dimensional Heisenberg monolayer with perpendicular ground-state spontaneous magnetization may have a temperature TR at which the spontaneous magnetization turns into the plane of the monolayer. The reorientation of the magnetization occurs via a phase transition. © 1990 The American Physical Society.
