Description
Summary:The Landau–Lifshitz equation modified by quantum fluctuations of the magnetic moment is proposed, on the basis of which several new effects in electron paramagnetic resonance in strongly correlated electronic systems are predicted, including an increase in the integral intensity and the appearance of universal relations connecting the contribution to the linewidth, the shift of the resonance field, and the integrated intensity. It is expected that the magnitude of the quantum corrections will depend on a single dimensionless parameter , where Δ M z and M 0 are the amplitude of fluctuations and the average value of the magnetic moment per magnetic ion, respectively.
