摘要

本研究深入研究了自旋电流诱导的现象，如自旋霍尔磁电阻和自旋塞贝克效应，特别是在低温下沉积在非共线磁体cocr2o4 （CCO）上的Pt薄膜。详细研究了自旋霍尔磁阻（SMR）和自旋塞贝克效应（SSE）的角依赖性。SMR和SSE信号的温度依赖行为都表现出与CCO不同磁相相关的明显变化。为了区分磁邻近效应的贡献，我们在pt - m3边缘进行了x射线磁二色性（XMCD）。来自Pt/CCO异质结构的XMCD数据表明，与Pt相关的任何磁矩，如果存在，都低于检测极限。这支持了观测到的信号主要来自SMR和SSE的概念。这项研究提供了对自旋电流驱动现象的见解，为潜在的自旋电子应用铺平了道路。

Spin Hall magnetoresistance and spin Seebeck effect in Pt |CoCr₂O₄ heterostructures.

This study delves into spin current-induced phenomena, such as spin-Hall magnetoresistance and the spin Seebeck effect within Pt films deposited on a noncollinear magnet, CoCr $_{2}$ O $_{4}$ (CCO), particularly at low temperatures. Detailed investigation of the angular dependencies of spin Hall magnetoresistance (SMR) and spin Seebeck effect (SSE) was carried out. The temperature-dependent behavior of both SMR and SSE signals exhibits a discernible variation correlated with different magnetic phases of CCO. To distinguish the contributions arising from magnetic proximity effects, we conducted X-ray magnetic dichroism (XMCD) at the Pt-M $_{3}$ edge. XMCD data from Pt/CCO heterostructures suggest that any magnetic moment associated with Pt, if present, is below the detection limit. This supports the notion that the observed signals primarily stem from SMR and SSE. This study offers insights into spin-current-driven phenomena, paving the way for potential spintronic applications.
