Application of Tsallis functions for analysis of line shapes in electron magnetic resonance spectra of magnetic nanoparticles

Abstract

An effective electron magnetic resonance study of nanoparticles requires, in addition to an adequate theory (which is absent nowadays), standard spectral characteristics making it possible to compare the spectra. For characterizing the electron magnetic resonance spectra of magnetic nanoparticles, it has been proposed to use the decomposition of the spectra using the parameters of Tsallis distributions (lines with smoothly varying shapes). This method has been tested on a two-component spectrum of colloidal magnetite nanoparticles and on poorly resolved broad spectra of iron-containing nanoparticles stabilized on microgranules.
