Ferromagnetic resonance as a diagnostic method of the quality and functional properties of multilayer structures

Abstract

The article presents the main results of an investigation into the structural and magnetic parameters of samples formed on single-crystal (MgO) and the amorphous substrates Si/SiO2 structures. In order to identify individual contributions and anisotropy constants, a series of experiments was carried out to investigate the angular dependence of the resonance field and linewidth of the FMR depending on the direction of the external magnetic field in the two geometries. Quality indicators such as the paramagnetic phase, the presence of impurities, and an analysis of the functional properties were assessed. The radiophysical methods features for the diagnosis of prospective structures were shown. Refs 17. Figs 3. Tables 2.
