论文摘要
人们普遍认为，磁场通过诱导库珀对的有序运动来抑制超导性。我们证明，磁场可以通过诱导超导冷凝物的运动来提供一系列超导相关性。在Rashba旋转轨道耦合的情况下，超导体/铁磁异质结构产生了这种效果。我们预测，通过磁场的应用，可以在距超导体/非电磁体界面在距离超导体/铁磁界面的大距离内打开的奇数旋转三个超导超导相关性。这表明这会导致约瑟夫森效应和超导体/铁磁性结构中状态的局部密度的异常行为。
It has been commonly accepted that magnetic field suppresses superconductivity by inducing the ordered motion of Cooper pairs. We demonstrate that magnetic field can instead provide a generation of superconducting correlations by inducing the motion of superconducting condensate. This effect arises in superconductor/ferromagnet heterostructures in the presence of Rashba spin-orbital coupling. We predict the odd-frequency spin-triplet superconducting correlations called the Berezinskii order to be switched on at large distances from the superconductor/ferromagnet interface by the application of a magnetic field. This is shown to result in the unusual behaviour of Josephson effect and local density of states in superconductor/ferromagnet structures.
