Toward intrinsic ultra-high-temperature ferromagnetism in a CrAuTe/graphene heterosystem.

Exploring intrinsic two-dimensional (2D) ferromagnetic (FM) materials with high Curie temperatures () and large magnetic anisotropy energies (MAE) is one of the effective solutions to develop materials for high-performance spintronic applications. Using density functional theory calculations and high-throughput computations, we predict an intrinsic bimetallic FM monolayer, CrAuTe, which has a large MAE and high . The results show that the value of the MAE can reach about 1.
