摘要：

Magnetocrystalline anisotropy arising from a crystal field of magnitude comparable with exchange has been studied using a spin-wave theory. The 'power law' temperature dependence of the anisotropy coefficients is modified at low temperatures, a result which is in agreement with the measurements of Rhyne and Clark. Values of crystal-field parameters deduced by comparison with experiment are a factor 2-3 larger than the results of screened point charge calculations.
