Excitation spectrum and magnetic dynamics of the Néel ensemble of antiferromagnetic nanoparticles in Mössbauer spectroscopy

A continual magnetic dynamics model of an ensemble of antiferromagnetic nanoparticles with uncompensated spin is developed that allows descriptions of the energy spectrum, magnetic dynamics, and Mössbauer spectra of antiferro- and ferromagnetic nanoparticles. Qualitative effects observed experimenta...

Description
Summary:A continual magnetic dynamics model of an ensemble of antiferromagnetic nanoparticles with uncompensated spin is developed that allows descriptions of the energy spectrum, magnetic dynamics, and Mössbauer spectra of antiferro- and ferromagnetic nanoparticles. Qualitative effects observed experimentally for almost half a century can be explained using this approach, and they can be described quantitatively.
