An Ab Initio Study of Monolayer Mn2Mg2X5 (X = S, Se), a Novel Family of 2D Half-Metallic Ferromagnets — •Soheil Ershadrad and Biplab Sanyal — Uppsala Univeristy, Uppsala, Sweden

Based on first principle calculations, we propose a family of stable 2D ferromagnets, Mn2Mg2X5 (X = S, Se), with a half-metallic electronic structure. They possess a high Curie temperature, and strong magnetocrystalline anisotropy. An indirect exchange interaction, mediated by chalcogen atoms, dominates in these crystals. Their half-metallicity and high-temperature magnetism render them suitable candidates for spintronic applications.
