Insulator -- half metallic transition by the tetragonal distortion: A first-principles study of strain-induced perovskite RbMnF${}_3$

N. Tsogbadrakh, N. Tuvjargal, Chun Feng +2

From the spin polarized density functional total energy calculations, we shown that the ground state of cubic perovskite RbMnF${}_3$ is an antiferromagnetic (AFM) insulator due to th…
