摘要

在Rashba自旋轨道相互作用系统中，Edelstein效应诱导了平面内磁化。然而，面外磁化对于铁磁存储器的开关更有用。本文基于一个简单的两波段模型，利用Rashba相互作用对p波磁体中的电场感应磁化进行了解析和数值研究。当p波磁体的nsamel矢量沿z方向时，产生面外磁化。我们还表明，在没有Rashba相互作用的情况下，不会产生磁化。电场感应磁化对未来基于p波磁体的铁磁存储器开关技术具有重要意义。2025年由美国物理学会出版

Out-of-plane Edelstein effects: Electric field induced magnetization in p -wave magnets

In-plane magnetization is induced by the Edelstein effect in a Rashba spin-orbit interaction system. However, out-of-plane magnetization is more useful for switching a ferromagnetic memory. We study analytically and numerically electric field induced magnetization in p-wave magnets with the aid of the Rashba interaction based on a simple two-band model. The out-of-plane magnetization is induced when the Néel vector of the p-wave magnet is along the z direction. We also show that no magnetization is induced in the absence of the Rashba interaction. The electric field induced magnetization will be useful for future switching technologies of ferromagnetic memories based on the p-wave magnet.
