A mechanism is proposed for FMR broadening and resonance frequency shift in a ferromagnetic conducting sample (hopping conductivity) of a doped lanthanum manganite due to the double exchange (DE) under FMR conditions (i.e. by the dynamic double exchange, DDE). It has been shown that the mechanism de...
