spin transport and spin filtering in superconductor nanostructures

超导体由于能够产生高度自旋极化的准粒子电流和自旋极化的三重态超电流，以及自旋和电荷自由度的分离，是研究自旋电子学功能的有希望的候选者。该项目的目标是通过在由超导体和铁磁绝缘体制成的混合结构中进行自旋滤波来研究纯无电荷自旋电流的产生和操纵。我们计划在超导体中实现一种基于自旋分裂的新型超导自旋阀，这可以作为未来超导自旋电子学器件的基石。

Superconductors are promising candidates for the investigation of spintronics functionality due to the ability to create highly spin-polarized quasiparticle currents and spin-polarized triplet supercurrents, as well as the separation of spin and charge degrees of freedom. The goal of the project is to investigate the creation and manipulation of pure chargeless spin currents by spin-filtering in hybrid structures made of superconductors and ferromagnetic insulators. We plan to implement a new type of superconducting spin-valve based on spin-splitting in the superconductor, which could be useful as a building block for future superconducting spintronics devices.
