Abstract

Density-functional studies of the electronic structures and exchange interaction parameters have been performed for a series of ferromagnetic full Heusler alloys of general formula Co $_2$ MnZ (Z = Ga, Si, Ge, Sn), Rh $_2$ MnZ (Z = Ge, Sn, Pb), Ni $_2$ MnSn, Cu $_2$ MnSn and Pd $_2$ MnSn, and the connection between the electronic spectra and the magnetic interactions have been studied. Different mechanisms contributing to the exchange coupling are revealed. The band dependence of the exchange parameters, their dependence on volume and valence electron concentration have been thoroughly analyzed within the Green function technique.
