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

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.

Magnetic Composites with Embedded Magnetite Nanoparticles: Preparation, Control of Physical Properties, Applications

The formation of nanocomposites with embedded magnetite nanoparticles using layer-by-layer deposition is described in this review. It was shown, that physical properties of these composites are controllable by the variation of the magnetic nanoparticles layers number in their structure. The review of some practical application of magnetic nanocomposite materials based on their controllable properties was carried out as well.
