The electronic structure and magnetic properties in the Ni2MnZ series, where Z=Al, Ga, In, Sn, Sb, are studied using the first first-principles methods within density functional theory. The formation energies of several kinds of defects (atomic swaps, antisites. vacancies) are estimated. It is shown that Ni-antisites on the Mn sublattice have the lowest formation energy in the investigated series.
