<p>A high-frequency magnetic ceramic comprises garnet ferrite represented by the formula AZB8-ZO12 wherein the site A comprises yttrium and the site B comprises iron, where Z is in the range of more than 3.00 to 3.09. The relative density of the high-frequency magnetic ceramic is at least 95%, the average grain diameter is at least 3 νm, and the 3σ value of the grain diameters is 2 νm or less wherein σ represents the standard deviation of the grain diameters. A high-frequency circuit component includes microwave magnetic composites composed of the high-frequency magnetic ceramic and central electrodes that are mutually insulated.</p> |
