Chamor T. Electromagnetic spin waves and oscillations of millimeter range in the multi-layer structures

The thesis are devoted to the investigation of the electromagnetic and spin oscillations and waves in the multi-layer structures. The main attention is paid to the experimental research of the spectrums peculiarities of elementary magnetic disturbances in epitaxial films of single-axis hexaferrites in the condition with the cylindrical domain structure (CDS) and parallel-plate domain structure (PPDS) and in the saturation area under normal magnetizing. In the paper the influence is being investigated of the substrate layer onto the parameters of the interaction of barium hexaferrite films with the ultrahigh frequency field, as well as the comparative analysis is conducted for the films with different thickness.
