Abstract	The Korringa-Kohn-Rostoker approximation method combined with coherent potential approximation (KKR-CPA) and the parameterization of Vosko, Wilk, and Nusair (VWN) for ab initio calculations have been used to study the magnetism impacts of the vanadium-and-chromium-doped and vanadium-and-chromium-co-doped FeS$_{2}$ pyrite. Our results show that the antiferromagnetic (AFM) stability belongs to super-exchange coupling type and then to the existing disordered local moment (DLM) in Fe$_{0.98}$V$_{0.02}$S$_{2}$. However, Fe$_{0.95}$Cr$_{0.05}$S$_{2}$ shows that the ferromagnetic (FM) stability belongs to double-exchange coupling type and is having a considered Curie temperature (T $_{C}$) which leads to significant magnetic proprieties. Moreover, 3d-3d hybridization of transition metals shows that is believed to result half-metal proprieties for the Fe$_{0.93}$V$_{0.02}$Cr$_{0.05}$S$_{2}$ system, so V and Cr could be interacting with 3p orbital of S. As a result, this forms the p-d orbital hybridization producing an efficient magnetic moment field to line up the V and Cr magnetic moment and stabilizing the half-metallic (FM) state, beside having a high magnetic moment and an evaluated useful T $_{C}$ in eventual spintronic applications.
