We investigated the magnetism and electronic structures for the layered structures consisting of (110) layers of zinc-blende CrAs and MnAs. We calculated the electronic structures for (CrAs)₃(MnAs)₃(110) superlattice consisted of alternating three layers of CrAs(110) and MnAs(110) by the full-potential linearized augmented plane wave (FLAPW) method. The calculated magnetic moment of Cr in interface layer (3.07 μ<SUB>B</SUB>) was slightly larger than that of Cr atom in center layer (3.06 μ<SUB>B</SUB>), while that of interface Mn atom (3.74 μ<SUB>B</SUB>) was slightly smaller than the value of Mn atom in center layer (3.76 μ<SUB>B</SUB>). The electronic structure and half-metallicity in this superlattice were discussed using the calculated density of states.
