Microwave magnetic excitations in U-type hexaferrite Sr${}_4$CoZnFe${}_{36}$O${}_{60}$ ceramics

M. Kempa, V. Bovtun, D. Repček +3

Microwave (MW) transmission, absorption, and reflection loss spectra of the ferrimagnetic U-type hexaferrite Sr${}_4$CoZnFe${}_{36}$O${}_{60}$ ceramics were studied from 100 MHz to 35 GH…
