论文摘要
通常认为，在低于临界温度的一定温度下，超导体（SC）的磁响应仅取决于其内在特性。在这里，我们表明，SC的机械旋转可以轻松地改变超导性被破坏的临界场的值（Type-1 SC）或涡流渗透到材料（type-2 SC）的（退出）中。这是由于外部场引起的Meissner电流的叠加以及机械旋转引起的SC表面上的自发电流。结果，根据材料的几何形式以及旋转和外部场的相对取向，可以增加或减少SC的临界场。
It is generally believed that, at a certain temperature below the critical one, magnetic response of a superconductor (SC) is determined solely by its intrinsic properties. Here we show that the mechanical rotation of a SC can easily change the values of the critical fields at which the superconductivity is destroyed (type-1 SC) or the vortices penetrate into (exit from) the material (type-2 SC). This is due to a superposition of the Meissner current induced by the external field, and the spontaneous current on the surface of the SC induced by the mechanical rotation. As a result, the critical fields of a SC can be increased or decreased, depending on the geometrical form of the material and the relative orientation of rotation and the external field.
