Spintronics: Large‐Spin‐Gap Nodal‐Line Half‐Metal and High‐Temperature Ferromagnetic Semiconductor in Cr2X3 (X=O,S,Se) Monolayers (Adv. Electron. Mater. 1/2020)

In article number 1900490, Fang‐Ping Ouyang, Xiang Xiong, and co‐workers propose a family of stable 2D honeycomb Kagome Cr2X3 (X=O,S,Se) monolayers through first‐principles calculations. Planar Cr2S3 and Cr2Se3 are ferromagnetic half‐metals with mirror symmetry protected nodal lines for spin‐down channels, while buckled Cr2O3 layers are ferromagnetic semiconductors with large out‐of‐plane magnetocrystalline anisotropy energy (MAE), and predicted Curie temperatures of 332 K under moderate biaxial tensile strain. These properties make such materials suitable for novel spintronic devices and exotic quantum applications.
