Changes in magnetic parameters of nickel zinc ferrite (NZF) ceramics have been monitored in situ during microwave H heating using an indigenous technique developed in the laboratory. The technique utilizes the concept based on combining a small measurement signal with a high power-processing signal, which permits a study on materials heated either in an electric or in a magnetic field of a TM103 single mode cavity. Coupling and decoupling of these two signals are suggested by the use of a simple arrangement. Experimental results obtained on various compositions of NZF ceramics up to 1200 °C are presented. The results indicate that the higher zinc end compositions of the ferrites demonstrate the phenomenon of decrystallization under the influence of microwave H.
