Microwave Absorption Spectra and Resonance Frequencies of a «Magnetic Nanocomposite Coating – Microstrip Line» Structure

Voronin Denis Viktorovich, Saratov State University

This paper aims to look into microwave absorption spectra of «magnetic nanocomposite coating – microstrip line» structure, containing magnetite Fe3O4 nanoparticles. The resulted spectra allowed to define the specific resonance frequencies of the structure under investigation and to figure out the material parameters of the nanocomposite coating, that are, an effective magnetization, a volume fraction of magnetic nanoparticles in the coating as well as a magnetic crystalline anisotropy filed. The results of this work may be used to design new magnetic materials containing magnetite nanoparticles for novel microwave devices with enhanced properties.
