Intrinsic ferromagnetism and the quantum anomalous Hall effect in two-dimensional MnOCl₂ monolayers

Abstract

Due to their potential application in spintronic devices, two-dimensional (2D) ferromagnetic materials are highly desired. We use first-principles calculations and Monte Carlo simulations to investigate the electronic structure and magnetic...

Multiferroicity in 2D MSX2 (M = Nb and Zr; X = Cl, Br, and I)

“…The CrOF 2 monolayer exhibits a half-metallic nature with intrinsic ferromagnetism (FM) and a high phase transition temperature. The Pmna -MnOCl 2 monolayer is an FM-stabilized semiconductor with an indirect band gap of 0.152 eV, while the Pmmn -MnOCl 2 monolayer is an FM Dirac semimetal with a Curie temperature of 910 K. 20 Uniaxial strain drives the magnetic phase transition in CrOF 2 , resulting in a high phase transition temperature. 21 2D NbOX 2 materials possess suitable conduction band minimums (CBMs) and valence band maximums (VBMs) for photocatalytic water splitting, which can be further tuned by stacking.…”
