Abstract
A standard multi-level relaxation model of magnetic dynamics of single-domain particles together with recently developed quantum-mechanical and continual models of specific thermo- and magnetic dynamics of antiferromagnetic particles were applied to analyse temperature series of Mössbauer spectra of Fe2O3 based nanoparticles. Advantages of these models, their comparison and further generalizations are discussed on the example of the particular experimental data.
