Abstract
Based on the theory of first principles spin-density functional calculations within the framework of the CA local density approximation, we examine the structural, elastic, electronic and magnetic properties of ternary alloys CdS and CdSe doped with manganese at x = 0.125. We found that Cd(0.875)Mn(0.125)Z (S, Se) materials are ferromagnetic in nature. The total and partial curves of density and the electronic bond structures of states show that Cd(0.875)Mn(0.125)Z (S, Se) are ferromagnetic and can be potentially good candidates for the spintronic applications.
