Monolayer and bilayer lanthanide compound Gd 2 C with large magnetic anisotropy energy and high Curie temperature

Comparing with transition metal compounds, lanthanide compounds hold promising potential as spintronic materials to generate large magnetic moments and strong magnetic anisotropic. By conducting in-depth theoretical calculations, we explored the electronic and magnetic properties of monolayer and bilayer Gd 2 C, the f-electron lanthanide compound. Monolayer Gd 2 C is a ferromagnetic (FM) half-metal with large band gap (1.68 eV) in the semiconducting spin-channel. It has large magnetic anisotropic energy (MAE) (703 μeV/Gd atom), and Curie temperature ( T_C ) of 322 K, above room temperature and higher compared with Gd metal and layered Gd 2 C. Under 5
