Abstract
The magnetic properties after sintering of NiZnCu ferrite from self-propaga ted powders were investigated. Results from frequency spectra showed very h igh initial permeability, high cutoff frequencies and stable quality factor values for the sintered ferrites. The reactivity, sintering temperature an d microstructure were correlated to the permeability. The magnetizing mecha nism of the materials mainly resulted from domain walls motion.
