We investigate quantum dynamics of the excited electronic states in the double-exchange model at half-filling by solving coupled equations for the quantum evolution of electrons and Landau-Lifshits-Gilbert equation for classical spins. The non-adiabatic quantum transitions driving the relaxation are coordinated through the self-organized space-time structure of the electron/spin dynamics leading to a resonant precession analogous to the ESR process.
