Abstract

The coupling between the longitudinal and transverse fluctuations in a spin s ferromagnet becomes significant above a crossover temperature T approximately=T_c/s. This coupling produces a splitting of the spin-wave resonance near the energy zJs, where z is the coordination number and J the coupling constant. The authors calculate the transverse mode frequencies and propose an experiment to detect the longitudinal fluctuations.
