论文摘要
在2D Spintronics的最新进展中，我们将欧盟存放在1H-WSE $ _2 $上，作为工程旋转轨道效果和浆果曲率的有前途的平台。通过基于密度功能理论的第一原理计算，我们表明欧盟/WSE $ _2 $表现出有趣的特性，例如高磁各向异性，山谷依赖性旋转和轨道角动量的极化以及其RashBA纹理。这些源自接口处的磁性和自旋轨道接近效应以及欧盟的本地化$ 4F磁矩与WSE $ _2 $的移动电荷载体之间的相互作用。我们在拟议的系统中发现明显的异常大厅效应。因此，我们促进了$ 4F $稀土金属，该金属沉积在过渡金属二分法中，作为2D Spintronics的有前途的平台。
Motivated by recent progress in 2D spintronics, we present Eu deposited on a 1H-WSe$_2$ as a promising platform for engineering spin-orbit effects and Berry curvature. By first-principles calculations based on density functional theory, we show that Eu/WSe$_2$ exhibits intriguing properties such as high magnetic anisotropy, valley-dependent polarization of spin and orbital angular momenta, and their Rashba textures. These originate from magnetic and spin-orbit proximity effects at the interface and the interplay between localized $4f$ magnetic moments of Eu and mobile charge carriers of WSe$_2$. We find a pronounced anomalous Hall effect in the proposed system. Thus, we promote $4f$ rare-earth metals deposited on top of a transition-metal dichalcogenides as a promising platform for 2D spintronics.
