New relaxation model for superparamagnetic particles in Mössbauer spectroscopy

A. M. Afanas'ev, M. A. Chuev

Insitute of Physics and Technology, Russian Academy of Sciences, Moscow

Abstract: A new model is suggested for the relaxation in a system of superparamagnetic particles. The model takes into account the interparticle interaction and ensuing smearing of energy levels for each individual particle, such that the relaxation between the particle states with opposite directions of magnetic moment never occurs as a transition between the states of the same energy. This generalization of the relaxation model accounts for the diversity of relaxation Mössbauer absorption spectra, allowing all the nonstandard features that were observed previously in the experimental spectra of systems with small-sized particles to be described on a qualitative level.
