We study tunneling currents in a model consisting of two nonunitary ferromagnetic spin-triplet superconductors separated by a thin insulating layer. We find a novel interplay between ferromagnetism and superconductivity, manifested in the Josephson effect. This offers the possibility of tuning dissipationless currents of charge and spin in a well-defined manner by adjusting the magnetization direction on either side of the junction.
我们研究了一个由两个非幺正铁磁自旋三重态超导体通过薄绝缘层分隔组成的模型中的隧穿电流。我们发现了铁磁性和超导性之间一种新颖的相互作用，体现在约瑟夫森效应中。这提供了通过调整结两侧的磁化方向以明确的方式调节无耗散电荷电流和自旋电流的可能性。
