摘要

二维范德华铁磁体有望最终实现微型自旋电子学和信息存储设备。在二维铁磁体中，它们都继承了它们的体祖先的磁性有序。本文报道了一种在室温下的二维铁磁性半导体，2h相二硒化钒(VSe2)，它仅在二维形式下显示铁磁性。这种二维铁磁半导体由于在二维极限下的结构各向异性而表现出增强的磁有序性。

Ferromagnetism in 2D Vanadium Diselenide

Two-dimensional (2D) van der Waals ferromagnets carry the promise of ultimately miniature spintronics and information storage devices. Among the 2D ferromagnets, all inherit the magnetic ordering from their bulk ancestors. Here we report a 2D ferromagnetic semiconductor at room temperature, 2H-phase vanadium diselenide (VSe₂), which shows ferromagnetic at the 2D form only. This 2D ferromagnetic semiconductor manifests an enhanced magnetic ordering owing to structural anisotropy at the 2D limit.
