| 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.

| Abstract: | 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. |
