<P>PROBLEM TO BE SOLVED: To provide a sintered magnetic oxide which has excellent magnetic properties in a range up to a high-frequency band of a several hundred MHz to GHz, contains no unusual phase other than Y-type hexagonal ferrite as less as possible, and can be fired at 1000°C or below, especially around 900°C, and to provide a high-frequency circuit part using the same. <P>SOLUTION: This magnetic oxide sintered compact contains Y-type hexagonal ferrite in an amount of ≥80%. The magnetic oxide sintered compact contains, as main components, 5-17 mol% copper oxide expressed in terms of CuO, 57-61 mol% iron oxide expressed in terms of Fe<SB>2</SB>O<SB>3</SB>, >0-25 mol.% MO (MO is at least one of NiO, ZnO, and MgO), and residual AO (AO is either BaO or SrO), and bismuth oxide (Bi<SB>2</SB>O<SB>3</SB>), borosilicate glass and boron zinc silicate glass or bismuth glass, as a sub-component. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
