从理论上研究了超导体-铁磁体多层中超导相的成核。当超导层很薄并且通过铁磁层中的断对解耦时，平行临界场表现出非线性温度依赖性和非单调厚度依赖性。还计算了与强调制涡旋的成核相对应的垂直临界场。理论结果与 V/Fe 多层膜的实验数据非常吻合。
Nucleation of the superconducting phase in superconductor-ferromagnet multilayers is studied theoretically. When the superconducting layers are thin and decoupled by pair breaking in the ferromagnetic layers, the parallel critical field exhibits a nonlinear temperature dependence and nonmonotonic thickness dependence. The perpendicular critical field, corresponding to the nucleation of strongly modulated vortices, is also calculated. The theoretical results are in good agreement with experimental data for V/Fe multilayers.
