Half-metallic substances are very interesting for spin-dependent electronics devices as they boost their magnetoresistance capacity. The effect of the crystal field and the exchange splitting as a function of the concentrations values has been also investigated. The evaluation of the Curie temperature variation T C for the three components stable in the ferromagnetic phase revealed values greater than 300 K for most cases. Furthermore, we have identified the type of mechanism of exchange interactions being double exchange for all components except M n case where we find that the responsible mechanism is the p- d exchange. The spin polarization at Fermi level is estimated and found to be around 100%. On the other hand, we have investigated and plotted the density of states (DOSs) which reveals that the doped compounds exhibit a half-metallic character. Based on the KKR-CPA method within the Generalized Gradient Approximation (GGA), we have calculated the total energy to determine the most stable state in the system and found it to be the ferromagnetic state for T i, V and C r-doped C d S, while it is the stabilization in spin glass states for M n and C o cases. In this paper, an ab initio study of the electronic and magnetic properties of C d S doped by the transition metal elements has been investigated.
