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

Abstract

This paper aims to look into microwave absorption spectra of «mag-netic nanocomposite coating – microstrip line» structure, containing magnetite Fe3O4 nanoparticles. The resulted spectra allowed to define the specific resonance frequencies of the structure under investiga-tion 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 crystal-line 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.
