在铁磁体/自旋单线态-超导体界面处,可以产生具有磁性不均匀性的自旋极化超电流。在这样的系统中,复杂的磁不均匀性使得自旋极化的超电流难以功能化。然而,铁磁/自旋三重态超导体结中的自旋极化超电流可以通过铜对的磁化和自旋之间的角度(d矢量)来控制,这可以有效地用于发展称为超导自旋电子学的研究领域。最近,我们发现了自旋三重态关联的诱导铁磁体SrRuO 3外延沉积在自旋三重态超导体Sr 2 RuO 4,没有任何电子自旋翻转散射。本文系统地研究了Au/SrRuO 3/Sr 2 RuO 4结中邻近效应对磁场的依赖性。研究发现,诱导三重态关联具有强烈的各向异性场响应。这种行为归因于Sr 2 RuO 4的d-矢量的旋转。这种各向异性行为与涡旋动力学相反。我们的结果将促进铁磁性和非常规超导之间的相互作用的研究。
Spin-polarized supercurrents can be generated with magnetic inhomogeneity at a ferromagnet/spin-singlet-superconductor interface. In such systems, complex magnetic inhomogeneity makes it difficult to functionalise the spin-polarized supercurrents. However, spin-polarized supercurrents in ferromagnet/spin-triplet-superconductor junctions can be controlled by the angle between magnetization and spin of Copper pairs (d-vector), that can effectively be utilized in developing of a field of research known as superconducting spintronics. Recently, we found induction of spin-triplet correlation into a ferromagnet SrRuO3epitaxially deposited on a spin-triplet superconductor Sr2RuO4, without any electronic spin-flip scattering. Here, we present systematic magnetic field dependence of the proximity effect in Au/SrRuO3/Sr2RuO4junctions. It is found that induced triplet correlations exhibit strongly anisotropic field response. Such behaviour is attributed to the rotation of the d-vector of Sr2RuO4. This anisotropic behaviour is in contrast with the vortex dynamic. Our results will stimulate study of interaction between ferromagnetism and unconventional superconductivity.
