Ground state study of Electronic and Magnetic Properties of Co2MnZ (Z = Ge, Sn) type Heusler Compounds: A first Principle Study

The structural optimization was performed based on generalized gradient approximation (GGA) followed by the calculation of electronic structure and magnetic properties on Co2MnGe and Co2MnSn. The calculation of electronic structure was based on local spin density approximation (LSDA) within full potential linear augmented plane wave (FPLAPW) method. We studied the structural, electronic and magnetic properties. The calculated density of states (DOS) and band structures shows the half-metallicity of Co2MnGe and Co2MnSn.
