Abstract

Barium ferrites in which Fe or Ba was replaced by various metal ion combinations were investigated. The coercivity, saturation, and remanent magnetization were determined, and X-ray spectra were recorded to detect impurities. The Cu-doped compounds considered exhibit a temperature coefficient of coercivity close to zero. Moreover, several barium ferrites with positive and negative temperature coefficients of coercivity could be prepared. Site occupancies in selected compounds were determined by Mossbauer spectroscopy
