摘要：

Ultrathin ferromagnetic films with perpendicular spin anisotropy can possess an alternating up-down stripe-domain structure, with widths L±δ. Considering the two inequivalent types of stripe domains to form a single unit, this structure may be thought of as a two-dimensional smectic crystal. It is subject to a weak stripe orientation energy. With increasing temperature the domain system changes from a smectic crystal phase to an "Ising nematic" phase, and then to a "tetragonal liquid" phase. We discuss its possible phase diagrams, in, T) space. This sequence of phases can occur whether or not the system ultimately undergoes a spin reorientation transition to a planar phase. © 1995 The American Physical Society.
