Abstract
The MF-RPA model for Ho90Tb10, developed previously, is utilized for calculating the c-axis spin-wave energies of Ho. The low-temperature spin waves in the conical and helical phases agree well with the experiments of Stringfellow et al. At higher temperatures the calculations indicate that the hexagonal anisotropy still has appreciable effects on the spin waves, studied experimentally by Nicklow.
