Recently, predictions have been made about quantum anomalous Hall (QAH) insulators in Lithium-decorated iron-based superconductor monolayer materials (LiFeX (X = S, Se and Te)) with very high Curie temperatures (0.00,0.00,1.00PRL 125, 086401 (2020)), which combine topological and ferromagnetic orders. It is interesting and useful to achieve the coexistence of intrinsic piezoelectricity, ferromagnetism, and nontrivial band topology in single two-dimensional (2D) materials, namely 2D… Expand

TLDR
By first-principles calculations, a family of 2D Janus monolayer Fe2IX (X = Cl and Br) with dynamic, mechanical, and thermal stabilities is predicted to be a room-temperature PQAHI and the combination of piezoelectricity, topological and FM orders makes the monolayers become a potential platform for multi-functional spintronic applications with a large gap and high TC.
