Electronic structures of MnB soft magnet

초록

We have calculated the electronic structure of MnB using first-principles calculations based on the density functional theory within the local-spin-density approximation. The temperature dependence of saturation magnetization [M-s(T)] was calculated by mean field approximation. The calculated density of states (DOS) shows that the energy region near the Fermi energy (E-F) is mostly attributed to the d bands of Mn. The saturation magnetizations (M-s) of MnB were calculated to be 964.5 emu/cm(3) (1.21 T) at 0 K and 859.3 emu/cm(3) (1.08 T) at 300 K. The calculated M-s at 300 K is in good agreement with experimental M-s of 851.5 emu/cm(3). (C) 2016 Author(s).
