First-principle calculations were performed within the framework of the density functional theory (DFT) using FP-LAPW method as implemented in WIEN2k code to determine the structural stability, electronic and magnetic properties of Rh₂CrGe_1-xAl_x (x = 0, 0.25, 0.50, 0.75 and 1). The results showed that for Rh₂CrAl and Rh₂CrGe, the Cu₂MnAl-type structure is energetically more stable than Hg₂CuTi-type structure at the equilibrium volume. The calculated densities of states for Rh₂CrAl and Rh₂CrGe show half-metallic and nearly half-metallic behavior, respectively. Rh₂CrGe_1-xAl_x (x = 0.25, 0.50, 0.75) these alloys show a half-metallic character, and these compounds are predicted to be good candidates for spintronic applications.
