三重态超导自旋阀的临界温度取决于超导体中的单线态对转换成三重态对的有效性，三重态对可以穿透铁磁体，从而驱动强邻近效应。在这里，我们比较了平面外场的依赖性的临界温度在过渡金属三重态自旋阀与其他等效样品中，其中的单重态-三重态转换自旋混合器铁磁体层被省略。我们报告了一个显着的场依赖性的样品之间的差异，这是一致的磁化取向依赖于自旋阀中的自旋混合效率。由AIP出版社出版。
The critical temperature of a triplet superconducting spin valve depends on the effectiveness of the conversion of singlet pairs in the superconductor into triplet pairs which can penetrate a ferromagnet and so drive a strong proximity effect. Here, we compare the out-of plane field dependence of the critical temperature in transition metal triplet spin valves with otherwise equivalent samples in which the singlet-triplet converting spin mixer ferromagnet layer is omitted. We report a significant field-dependent difference between the samples, which is consistent with a magnetisation orientation dependent spin mixing efficiency in the spin valve.
