Abstract

This article presents the results of experimental studies of the effect of proximity of a ferromagnetic dielectric with in-plane magnetization (Y₃Fe₅O₁₂) on the superconducting transition in planar hybrid Y₃Fe₅O₁₂/Nb and Y₃Fe₅O₁₂/Al structures. The temperature dependence of the superconductor resistance changes due to the proximity of the magnetic dielectric: the superconducting transition temperature is lowered, and the transition broadens. The dependence of these effects on the mutual orientation of current in the superconductor and in-plane magnetization in the dielectric is revealed. The role of spin–orbit interaction at the superconductor/magnetic dielectric interface and symmetry violation in the superconductor with one of its surfaces being in contact with the magnetic material (and the other being free) is discussed.

钇铁石榴石-超导体结构中的不可逆性

摘要

本文介绍了在平面杂化Y ₃ Fe ₅ O ₁₂ / Nb和Y ₃ Fe _5中铁磁介电体具有平面内磁化强度（Y ₃ Fe ₅ O ₁₂）的超导转变的实验研究结果。Ø ₁₂/ Al结构。超导体电阻的温度依赖性由于磁性电介质的接近而改变：超导转变温度降低，转变变宽。揭示了这些效应对超导体中电流相互定向和电介质中面内磁化强度的依赖性。讨论了自旋-轨道相互作用在超导体/磁性介电界面上的作用以及超导体的对称性破坏，其中一个表面与磁性材料接触（另一个表面是自由的）。
