摘要
Half-metallic ferromagnets(HMFs)that possess intriguing physical properties with completely spin-polarized current are key candidates for high-efficiency spintronic devices.However,HMFs that could simultaneously have high Curie temperature(Tc),wide half-metallic gap(ΔHM),and large bulk magnetocrystalline anisotropy energy(MAE)are very rare,which significantly restrict their room-temperature(RT)applications.In this article,through materials screening in layered halide double perovskites(LHDPs).
