The orbital moment in CoO
Abstract
Description
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. The orbital moment of 1.38 μ_{B} amounts at 0 K, in the magnetically-ordered state, to more than 34% of the total moment (4.02 μ_{B}) and yields the L/S ratio of 1.04, close to the experimental value.
