基于唯象的Ginzburg-Landau模型，计算了磁通耦合超导体/铁磁体（S/F）混合体在畴壁非均匀磁场作用下形成的畴壁超导沟道的临界电流.结果表明，在畴壁超导态下，这种S/F系统的载流能力在注入电流相对于宇称破缺矢量的正、负方向上是不同的，其大小正比于μ ×M？>因此由铁磁衬底中的局部磁化矢量M（r）确定。我们证明，在这样的S/F系统的实现所谓的二极管效应是可能的横向无限和介观结构。
On the basis of the phenomenological Ginzburg–Landau model we calculate the critical current of the domain-wall superconducting channel formed in flux-coupled superconductor/ferromagnet (S/F) hybrids in the presence of the nonuniform magnetic field of the domain walls. It is shown that the current-carrying ability in such S/F systems in the domain-wall superconducting state differs for the positive and negative directions of the injected current with respect to the parity-breaking vector, which is proportional to ∇×M?> and thus determined by the local magnetization vector M(r) in the ferromagnetic substrate. We demonstrate that in such S/F systems the realization of the so-called diode effect is possible for both laterally infinite and mesoscopic structures.
