摘要：

We report on vacancy induced half-metallicity in the prototype Mott-insulating substances MnO and NiO. By embedding a cation vacancy into a magnetic system a new road opens up to the construction of half-metallic antiferromagnets. For Ni0.97O we find a half-metallic antiferromagnet, a system hitherto only proposed for complicated crystal structures.
