Abstract
A model of an amorphous ferromagnet in which a certain number of atoms forms two-level systems is considered. Relaxation time of such systems due to the interaction with spin waves is calculated and it is shown that this time can be comparable to the phonon relaxation time. The spin wave damping in such ferromagnet is determined and the magnetic contribution to the thermal conductivity is calculated.
