In M-type Ba ferrite; BaFe₁₂O₁₉, which has uniaxial anisotropy in the c-axis direction and exhibits large saturation magnetization at room temperature, the composition of the study example of soft magnetization and the study example of improving coercive force while maintaining saturation magnetization. We confirmed the magnetic characteristics of Ba_1-YLa_YFe_12-2X-Y(Co, Ti) _XCo_YO₁₉ with a mixed composition, and examined its application to an electromagnetic interference suppressor for the GHz band.
