Microwave magnetic excitations in U-type hexaferrite Sr4CoZnFe36O60 ceramics
Original language description
Microwave (MW) transmission, absorption, and reflection loss spectra of the ferrimagnetic U-type hexaferrite Sr4CoZnFe36O60 ceramics were studied from 100 MHz to 35 GHz at temperatures between 10 and 390 K. Nine MW magnetic excitations with anomalous behavior near ferrimagnetic phase transitions were revealed. Six magnetic modes are assigned to dynamics of the magnetic domain walls and inhomogeneous magnetic structure of the ceramics, to the ferromagnetic resonance (FMR), and to the higher-frequency magnons. The high-frequency FMR component critically slows down to phase transition. At room temperature, FMR splitting and suppression of the higher-frequency modes were revealed under the weak bias field (300–700 Oe). The high number of magnetic excitations observed in the MW region confirms the suitability of using hexaferrite Sr4CoZnFe36O60 ceramics as MW absorbers, shielding materials and highly tunable filters.
