• The magnetic susceptibility and antiferromagnetic resonance of CoO are studied on the basis of Kanamori's theory, in which the residual orbital angular momentum plays an important role in the magnetic properties of CoO. The parallel susceptibility does not vanish at 0°K due to the unquenched orbital angular momentum. The calculated parallel, perpendicular, and powder susceptibilities are in good agreement with measured values. The antiferromagnetic resonance modes and frequencies are calculated by the method of using fictitious magnetic fields. In the absence of an external field there are four modes, which are pair-wise degenerate. The obtained frequencies at O°K are 5.76×10^<12> sec^<-1> and 16.61x10^<12> sec^<-1>, which correspond to far-infrared wavelengths of 52.O microns and 18.1 microns, respectively.
