Abstract

The electronic structures of MnGe were studied by density functional theory. The B20 crystal structure plays an important role to make electronic properties of this compound. The electromagnetic characteristics of MnGe were compared with those of MnSi due to same crystal structure. The value of magnetic moment between two compounds has a large difference, which comes from the density of states. MnGe shows the half-metal characteristics. It has $2.0_{\mu B}$ magnetic moment which is 5 times that of MnSi.
