Quaternary Heusler alloy CoNbMnGa as ferromagnetic semiconductor
We have investigated Quaternary Heusler alloy CoNbMnGa under the density functional formalism utilizing Wein2k simulation package. The structural results reveal that CoNbMnGa alloy is stable in Y1 type structure with a relaxed lattice constant of 5.92Å under ferromagnetic phase. Our results affirm t...

| description | We have investigated Quaternary Heusler alloy CoNbMnGa under the density functional formalism utilizing Wein2k simulation package. The structural results reveal that CoNbMnGa alloy is stable in Y1 type structure with a relaxed lattice constant of 5.92Å under ferromagnetic phase. Our results affirm that CoNbMnGa exhibits semiconducting nature under modified version of Beck-Johnson potential with a gap of 0.30 eV and 0.27eV in up and down spin channels respectively. The existence of gap is elaborated through a schematic representation with possible d-d hybridization between the transition metals Co, Nb and Mn. |
