Electronic band structures of NiAs-type compounds. I. Nonmagnetic state

Abstract
Electronic band structures of several transition-metal pnictides and chalcogenides, MnAs, MnSb, CrAs, CrSb, VS and TiSe, having the NiAs-type crystal structure are calculated for the non-magnetic state by a self-consistent augmented-plane-wave (APW) method. The calculated energy dispersion and density of states are discussed in connection with magnetic ordering. The band structure of MnAs having the MnP-type structure is also calculated by the APW method.
