本文研究了扩散状态下通过长铁磁双层膜的约瑟夫森电流。对于非共线磁化，我们发现，电流相位关系是由它的二次谐波，这对应于两个三重态电子对的长程相干传播占主导地位。
We study the Josephson current through a long ferromagnetic bilayer in the diffusive regime. For noncollinear magnetizations, we find that the current-phase relation is dominated by its second harmonic, which corresponds to the long-range coherent propagation of two triplet pairs of electrons.
