The full potential linear augmented plane wave (FPLAPW) based on density-functional theory (DFT) is employed to study the structural, electronic and magnetic properties of transition metal Co doped CdTe. We have analyzed the structural parameters, charge and spin densities, total and partial densities of states within the generalized gradient approximation (GGA). The results show a Half-Metallic Dilute Magnetic Semiconductors (HM-DMS) character with an important magnetic moment. The results obtained, make the CoxCd1−xTe a potential promising candidate for application in spintronics.
