摘要	The electronic structure and electrical transport properties of the cubic perovskite (E2(1)) oxide barium manganese (BaMnO(3)) and the BaMnO(3)/BaTiO(3) superlattice are investigated by the density-functional theory in this report. The results show that the cubic BaMnO(3) exhibits half-metallic properties with an integral magnetic moment of 3.000 mu(B) per unit cell in its metastable state, while the BaTiO(3)/BaMnO(3) superlattice also shows a stable half-metallic ground state with an integral magnetic moment of 12.000 mu(B) per unit cell. In conclusion, we show that the construction of a BaMnO(3)/BaTiO(3) superlattice could stabilize the cubic metastable phase of the BaMnO(3) and provide a stable half-metallic material for potential applications in spintronic devices.
