The magnetic anisotropy constant Cr_2O_3 arising from the dipolar interactions among the chromic ions was calculated to be -0.059cm^<-1> per ion at absolute zero, and the magnetic anisotropy constant due to the crystalline field combined with the spin-orbit coupling was estimated from the fine-structure coupling constant of ruby and compared with that deduced from the antiferromagnetic resonance experiment by Dayhoff. The value from ruby is too large. The temperature dependence of the anisotorpy constant and that of the antiferromagnetic resonance frequency at zero field are discussed.
