摘要：

It is shown that an orbital-polarization correction to a spin-polarized band-structure calculation leads to an insulating gap for CoO, in sharp contrast to a standard band calculation. Orbital-polarization instabilities, though, are not found for FeO and La2CuO4. © 1990 The American Physical Society.
