The half-metallic properties of the (110) and (001) surfaces of rocksalt VPo: A first-principles study

► The bulk half-metallicity of VPo with rocksalt structure. ► The surface stability of RS VPo (110) and (001) surface. ► The half-metallicity is preserved at the (110) and (001) surfaces. ► We discuss the atomic spin magnetic moments of the surface.
