摘要：

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