Abstract
A self-consistent study of the spin diffusion in the double-exchange magnets within the framework of DMFT is discussed. This nonperturbative approach allows to calculate the spin-diffusion coefficient at any temperature down to a transition point. A good agreement with the experiments in the ferromagnetic CMR manganites and earlier work is shown.
