Abstract
Abstract: The stability, structural, electronic and magnetic properties of the doped Heusler compounds Co2MnGa1−xAlx with (x= 0, 0.25, 0.50, 0.75 and 1) were studied theoretically by using first-principles density functional theory within the generalized gradient approximation (GGA) scheme. The magnetic state is found to be energetically more favorable than the non-magnetic one. The calculated results reveal that with increasing Al concentration, the lattice parameter slightly decreases. Furthermore, the calculated densities of states for Co2MnGa, Co2MnAl and Co2MnGa1-xAlx (x = 0.25, 0.50 and 0.75) show a half-metallic behavior. Keywords: Heusler, Half metallic, Co-based heusler, Magnetic moment.
