One dimensional Cherenkov processes in ferromagnetic insulators are studied with perturbation theory under the constraint condition of conservation of energy and momentum. It is shown that the magnon-phonon interaction channels are limited and wave number dependent, which result in, respectively, 1 / k 2 and 1 / k 4 dependence of the lifetime and the relaxation time of long wavelength magnons. The reciprocal of relaxation time between magnons and phonons, 1 / τ m p, is found to be a linearly increasing function of the temperature in the high temperature regime. Based on the Sanders-Walton model, we further show that when a thermal (phonon) gradient is applied along the system, the temperature difference between the phonon bath and the magnons with wave-vector k becomes more pronounced as k decreases.
