摘要：
This paper theoretically studies Josephson spin current through triplet superconductor/ferromagnet/triplet superconductor junctions.At the ferromagnet/superconductor interfaces,the ferromagnetic scattering potential gives rise to coupling between the Andreev bound states and lifts their spin degeneracy.These spin-split Andreev states carry the Josephson spin current through the junctions.The generated spin supercurrent can be controlled by the magnetization of a ferromagnetic thin layer and bias voltage across the junctions.
