The authors have studied the ESR of a concentrated spin glass as a function of temperature and applied an AC microwave field. On increasing this field beyond a certain small value, a shift in the resonance position and a non-linear increase in its intensity was found. The authors note some qualitative similarities between these effects and both plastic flow and depinning of charge and spin density waves.
