Abstract

Electronic band-structures of the hypothetical zinc-blende phase of MnAs and the (MnAs)1(GaAs)1(0 0 1) superlattice are calculated by using the full-potential linearized augmented-plane-wave method in order to discuss the effect of Mn-substitution for Ga in GaAs on their electronic and magnetic properties. The magnetic polarization antiparallel to the Mn moment is induced at the As site in the ferromagnetic state of both systems, which indicates the antiferromagnetic coupling between Mn-spins and valence-band carriers having mainly As 4p character.
