The orbital and spin moment of the Co2+ ion in CoO has been calculated within the quasi-atomic approach with taking into account the intra-atomic spin-orbit coupling and crystal field interactions. The orbital moment of 1.38 mB amounts at 0 K, in the magnetically-ordered state, to more than 34% of the total moment 4.02 mB and yields the L/S ratio of 1.04, close to the recent experimental value. This paper has been motivated by a recent paper in Phys. Rev. B 65 (2002) 125111, in which a presented theoretical approach was unable to calculate the orbital moment.
