“…The corresponding result for the energy of the long-wavelength spin waves is also in accordance with experiment (Houmann et a1 1975). We may therefore conclude that the dynamics of the spin-lattice system are well understood, although which mechanism is responsible for the magnetic absorption peak close to the transition at H,, observed by for instance Hart and Stanford (1971), is still not clear. The measuring frequency used by these authors, 24 GHz, is small compared with the spin-wave frequencies.…”

The dependence of ch6 in ferromagnetic Tb on a magnetic field applied along a hard axis in the basal plane has been studied experimentally. It has been predicted that c66 should vanish at the second-order transition from a phase where the magnetisation is parallel to the field to a phase which has a finite moment perpendicular to the field. Although it has not been possible to detect the ultrasonic waves in the close neighbourhood of the transition, cS6 is found to be substantially reduced at fields slightly higher than the critical value. The observed behaviour of c66 can be described quite accurately, at all temperatures below the Curie point, by a random-phase theory without the use of any free parameters,
