Sorochak A. Millimeter band spin-wave resonators based on uniaxial hexaferrites

The dissertation is devoted to the experimental investigation of the spectral features of millimeter band standing magnetostatic waves in the spin-wave resonators based on single-crystal M-type hexaferrite with a different type of domain structure. For the first time there was experimentally obtained the phenomenon of hybridization of the electromagnetic-spin oscillations in the composite structure single-crystal hexaferrite--dielectric resonator in multidomain area. The prototype of self-biased millimeter band notch filter with hexaferrite element has been realized. First, the idea of implementation of the high-frequency hysteresis phenomenon in single-crystal M-type hexaferrite was proposed and realized to create the prototype of a millimeter band pulse-switchable resonator.
