摘要：

Calculations are presented for the energies of magnons in NiO, MnO and α-MnS. The density of magnon states of these crystals is found to have two peaks labelled here as E1 and E2. The dispersion relations exhibit the symmetry predicted by Cracknell and Joshua. An anisotropic contribution arising from magnetic dipole interactions has been included and compared with a uniaxial anisotropy.
