摘要

我们从理论上考虑了一个由铁磁绝缘体（FI）和二维电子气（2DEG）组成的具有拉什巴和德雷斯豪斯型自旋轨道相互作用的结。利用玻尔兹曼方程，我们计算了当施加铁磁绝缘体和二维电子气之间的温差时，反向拉什巴-爱德斯坦效应在二维电子气中诱发的电流。我们阐明了诱导电流如何取决于 FI 的磁化方向、2DEG 费米面上的自旋纹理和温度。我们的结果为准确分析热自旋注入诱导的反向拉什巴-爱德斯坦效应奠定了重要基础。

Theory of the inverse Rashba-Edelstein effect induced by thermal spin injection

We theoretically consider a junction composed of a ferromagnetic insulator (FI) and a two-dimensional electron gas (2DEG) with Rashba- and Dresselhaus-type spin-orbit interactions. Using the Boltzmann equation, we calculate an electric current in 2DEG induced by the inverse Rashba-Edelstein effect when imposing the temperature difference between the FI and 2DEG. We clarify how the induced current depends on the magnetization direction of the FI, spin texture on the Fermi surface of 2DEG, and temperature. Our result provides an important foundation for an accurate analysis of the inverse Rashba-Edelstein effect induced by thermal spin injection.
