论文摘要
范德华（Van der Waals）（VDW）磁铁是调整具有巨大潜在旋转物应用潜力的二维（2D）磁性的理想平台，并经过深入研究。但是，对于这些抗磁磁系统中磁性的微观起源知之甚少。我们使用X射线光发射电子显微镜来解决VDW抗铁磁铁FEPS3的电子和磁性，并向单层。我们的实验表明，巨大的平面外磁各向异性为每一个fe离子22 meV，并伴随着未淬灭的磁轨道矩。此外，我们的计算表明，FEPS3中的伊斯丁磁性是Fe 3D电子系统的自旋轨道纠缠的可见表现。
Van der Waals (vdW) magnets are an ideal platform for tailoring two-dimensional (2D) magnetism with immense potential for spintronics applications and are intensively investigated. However, little is known about the microscopic origin of magnetic order in these antiferromagnetic systems. We used X-ray photoemission electron microscopy to address the electronic and magnetic properties of the vdW antiferromagnet FePS3 down to the monolayer. Our experiments reveal a giant out-of-plane magnetic anisotropy of 22 meV per Fe ion, accompanied by unquenched magnetic orbital moments. Moreover, our calculations suggest that the Ising magnetism in FePS3 is a visible manifestation of spin-orbit entanglement of the Fe 3d electron system.
