摘要：

We investigated the influence of Li and F adsorption on the ferromagnetism and magnetic anisotropy energy of CrBr(3)monolayer based on the first-principles calculations. It is observed that Li adsorption can dramatically enhance its ferromagnetism, and tune its easy magnetization axis to the in-plane direction from original out-of-plane. The monotonic enhancement of in-plane magnetism in CrBr(3)as the coverage of Li increases is attributed to electrostatic doping induced by charge transfer between Li atoms and Br atoms. By contrast, the F adsorption reduces the out-of-plane magnetism in CrBr(3)as the coverage of F increases, but keeps the original easy magnetization. Our results may open new promising applications of CrBr3-based materials in spintronic devices.
