POLYCRYSTALLINE CERAMIC MAGNETIC MATERIAL, MICROWAVE MAGNETIC COMPONENTS, AND IRREVERSIBLE CIRCUIT DEVICES MADE BY USING THE SAME |
| 摘要 |
<p>A polycrystalline ceramic magnetic material which has a basic composition represented by the general formula: (Y<SUB>3-x-y-z</SUB>Bi<SUB>x</SUB>Ca<SUB>y</SUB>Gd<SUB>z</SUB>)(Fe<SUB>5-a-ß-?-e</SUB>In<SUB>a</SUB>Al<SUB>ß</SUB>V<SUB>?</SUB>Zr<SUB>e</SUB>)O<SUB>12</SUB> (with the proviso that the following relationships by atomic ratio are satisfied: 0.4<X<1.5, 0.5<y<1, 0<z<0.5, y+z<1.3, 0<a<0.6, 0<ß<0.45, 0.25<?<0.5, 0<e<0.25, and 0.15<a+ß<0.75) and which consists mainly of a phase having garnet structure and permits burning at 850 to 1050°C.</p> |
