In this work we present the influence of atomic disorder on the electronic and magnetic properties of Ni_{2}MnGa_{1-x}Ge_{x} and Ni_{2}MnSn Heusler alloys. Ab initio band calculations were performed for the experimental lattice parameters. We applied SPR-KKR-CPA methods in the local spin density approximation.
