abstract = {Slater-Pauling (SP) rules connect the magnetic and
electronic properties of the half-metallic (HM)
Heuslercompounds. Employing first-principles electronic
structure calculations we explore the validity of the SP
rulesin the case of transition from HM semi-Heusler
compounds to various cases of HM full-Heusler compounds.We
show that the coherent-potential approximation yields
half-metallicity and thus a generalized version of theSP
rules can be derived. On the contrary, supercell
calculations, which are expected to describe the
experimentalsituation more accurately, show that the energy
gap considerably shrinks for the intermediate compounds and
inseveral cases the half-metallicity is completely
destroyed. The origin of this behavior is attributed to the
voids,which influence the symmetry of the lattice.},
