UI_{3}: a high Curie temperature felectron twodimensional magnet
Abstract
Based on density functional theory calculations and Monte Carlo simulations, we propose UI_{3} monolayer as a candidate of felectron twodimensional magnet. The UI_{3} monolayer has two kinds of crystal structures, which are rectangular and hexagonal, respectively. Our calculations show that both of them have ferromagnetic ground state, and the hexagonal structure is more stable than the rectangular one. Notably, the hexagonal UI_{3} monolayer has a 110 K Curie temperature. Furthermore, the large magnetic anisotropy, strong exchange interactions, and heavy spinorbit couplings enable the hexagonal UI_{3} monolayer to be an promising candidate material for future spintronic applications.
