Study of structural, electronic and magnetic properties of Rh2MnX (X=Al, Ge and Sn) Heusler alloys using GGA-WC and GGA+U approaches

We have performed first-principle calculations of the structural, electronic and magnetic properties of Rh2MnAl, Rh2MnGe and Rh2MnSn Heusler alloys, using the full-potential linearized augmented plane wave (FP-LAPW) scheme within the GGA-WC and GGA+U. Results are given for the lattice parameters, the bulk modulus and its pressure derivative. The total magnetic moments increase with increasing atomic number X. Also, we presented results of the band structure and the density of states. The electronic structure in the ferromagnetic configuration shows metallic character.
