利用含时Ginzburg-Landau理论，对手征p波超导体中多畴态的磁化过程进行了模拟研究。外场以无核涡的形式穿过畴壁进入内部，形成涡面结构。我们发现，随着磁场的增加，畴壁移动，使不稳定的畴收缩消失。因此，在更高的场实现单畴结构。
A simulation study for the magnetization process is performed for the multi-domain state in a chiral p-wave superconductor, using the time-dependent Ginzburg-Landau theory. The external field penetrates inside as core-less vortices through the domain wall, forming the vortex sheet structure. We find that, with increasing magnetic fields, the domain walls move so that the unstable domains shrink to vanish. Therefore, the single domain structure is realized at higher fields.
