摘要：

An interplay between possible mechanisms of magnetic and charge relaxation in itinerant electron ferromagnets is investigated. It is shown that non-linear ones due to emission (absorption) of spin or charge fluctuations by magnons may dominate giving rise to non-linear quasielastic spin and charge fluctuations observed in the colossal magnetoresistive manganites.
