摘要:

我们展示了一个独特的前景,诱导各向异性的涡旋钉扎和操纵的方向运动的涡旋使用的条纹域图案的单轴磁性薄膜中的超导/铁磁混合。我们的观察结果可以描述的模型,它认为磁荷的涡旋和表面磁荷的域之间的相互作用,导致增强钉扎的涡旋畴壁。

英文摘要:

We demonstrate a unique prospect for inducing anisotropic vortex pinning and manipulating the directional motion of vortices using the stripe domain patterns of a uniaxial magnetic film in a the superconducting/ferromagnetic hybrid. Our observations can be described by a model, which considers interactions between magnetic charges of vortices and surface magnetic charges of domains resulting in the enhanced pinning of vortices on domain walls.
