코발트를 첨가한 Mn-Zn Ferrite의 자기적 성질에 관한 연구
김상한,이정식,한종린 慶星大學校 1992 論文集 Vol.13 No.2
Effects of CoO additives on the magnetic properties of Mn-Zn ferrites are described. The six kinds of ferrites are prepared by the conventional ceramic method. The crystal structure of these samples is confirmed with the spinel structure by X-ray diffraction experiment, and the lattice constant is about 8.49Å. The Curie temperature of the samples increases with increased CoO contents on the initial permeability and temperature graph. The initial permeability decreases slowly as frequency increases.
