Original Paper


First-principles calculations within full-potential linear-augmented plane-wave method using the generalized gradient approximation were carried out for the electronic and magnetic properties of the Co2CrGa1−x Si x Heusler alloys. The electronic structure calculations show a conservation of the minority spin gap supporting the half-metallic character of the Co2CrGa1−x Si x alloys. The substitution of Ga by Si results in linear increasing of total magnetic moment as silicon concentration increases following the Slater–Pauling rule that is in agreement with experimental data.
