Due to the opposite natures of superconducting and ferromagnetic order parameters, hybrid bilayers systems have gained huge attention in past decades. Here we report manipulation of superconductivity by the orientation of the domain wall in such superconducting–ferromagnetic bilayers based on the phase-field model. The phase of the primary order parameter in the Ginzburg–Landau model was used to describe the vortex dynamics path in the superconductor. Vortices were observed to follow the available path within domain centers perpendicular to the applied current, under the Lorentz force. Applied current was observed to follow the spatial path described by the ferromagnetic domain walls in the superconductors, where in the absence of such clear paths current was observed to form leakage channels from within the domain centers. Carrier concentration, supercurrent density, and energy components in the superconductor were observed to strongly depend on the orientation of the domain wa...

超导体-铁磁体双层中的畴壁调谐超导性

由于超导和铁磁有序参数的相反性质，在过去的几十年中，混合双层系统受到了广泛的关注。在这里，我们报告根据相场模型，通过这种超导铁磁双层中畴壁的取向来操纵超导。Ginzburg–Landau模型中的一次阶参数的相位用于描述超导体中的涡旋动力学路径。在洛伦兹力的作用下，观察到涡流沿垂直于外加电流的畴中心内的可用路径运动。观察到施加的电流遵循超导体中的铁磁畴壁所描述的空间路径，在这种情况下，如果没有这种清晰的路径，则观察到电流会从畴中心形成泄漏通道。载流子浓度
