<P>PROBLEM TO BE SOLVED: To provide a low-loss ceramic magnetic body for high frequency. <P>SOLUTION: In the ceramic magnetic body, a main phase has a spinel-type crystal structure. The compositional ratios of Fe, Co and Zn expressed in terms of Fe<SB>2</SB>O<SB>3</SB>, CaO and ZnO are within a compositional range surrounded by compositions 39.5:53:7.5 mol%, 39.5:48:12.5 mol%, 20:67.5:12.5 mol%, and 20:55:25 mol%. The ceramic magnetic body has a small temperature change of μ', and μ" is small up to several GHz. Thus the ceramic magnetic body can be used as the low-loss ceramic magnetic body for high frequency. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
