      abstract     = {We study the effect of the nonmagnetic 3d atoms on the
                      magnetic properties of the half-metallic (HM) semi-Heusler
                      alloys Co1-xCuxMnSb and Ni1-xCuxMnSb (0 <= x <= 1) using
                      first-principles calculations. We determine the magnetic
                      phase diagram of both systems at zero temperature and obtain
                      a phase transition from a ferromagnetic to an
                      antiferromagnetic state. For low Cu concentrations the
                      ferromagnetic Ruderman-Kittel-Kasuya-Yosida (RKKY)-type
                      exchange mechanism dominates, while the antiferromagnetic
                      superexchange coupling becomes important for larger Cu
                      content. A strong dependence of the magnetism in both
                      systems on the position of the Fermi level within the HM gap
                      is found. Obtained results are in good agreement with the
                      available experimental data.},
