The high-frequency properties of a composite resonator comprised of a microwave dielectric and a weak ferromagnet were investigated in the X-band. It was shown that inclusion of the weak ferromagnetic phase leads to possibility of magnetic field control over the resonator frequency, Q-factor and transmission characteristics that are in qualitative accordance with the predictions of perturbation theory. Magnetic field tunable change in insertion losses up to 16 dB and resonance frequency tuning up to 85 MHz have been observed. Such resonators are of interest for application in frequency agile devices with electronically tunable electrodynamic characteris- tics for the mm and sub-mm wave bands.
