Abstract
Official abstract text for this publication.
A magnetic composite contains a ferrite composition and zinc silicate. The ferrite composition is composed of a spinel ferrite and bismuth oxide present in the spinel ferrite, and the percentage by weight of bismuth oxide to the whole magnetic composite is about 0.025% by weight or more and about 0.231% by weight or less (i.e., from about 0.025% by weight to about 0.231% by weight). The percentage by weight of zinc silicate based on the total weight of zinc silicate and the spinel ferrite is about 8% by weight or more and about 76% by weight or less (i.e., from about 8% by weight to about 76% by weight).

What is claimed is: 1 . A magnetic composite comprising a ferrite composition and zinc silicate, wherein: the ferrite composition is composed of a spinel ferrite and bismuth oxide present in the spinel ferrite, and a percentage by weight of bismuth oxide to the whole magnetic composite is from about 0.025% by weight to about 0.231% by weight; and a percentage by weight of zinc silicate based on a total weight of zinc silicate and the spinel ferrite is from about 8% by weight to about 76% by weight. 2 . The magnetic composite according to claim 1 , wherein the percentage by weight of zinc silicate based on the total weight of zinc silicate and the spinel ferrite is from about 8% by weight to about 25% by weight. 3 . An electronic component comprising a body as a stack of a plurality of magnetic layers, outer electrodes on an outer surface of the body, a coil conductor inside the body, and extended conductors electrically coupling the outer electrodes and the coil conductor together, wherein the body is made of a magnetic composite according to claim 1 . 4 . An electronic component comprising a body as a stack of a plurality of magnetic layers, outer electrodes on an outer surface of the body, a coil conductor inside the body, and extended conductors electrically coupling the outer electrodes and the coil conductor together, wherein the body is made of a magnetic composite according to claim 2 . 5 . The magnetic composite according to claim 1 , wherein the percentage by weight of bismuth oxide to the whole magnetic composite is from about 0.036% by weight to about 0.21% by weight. 6 . The magnetic composite according to claim 2 , wherein the percentage by weight of bismuth oxide to the whole magnetic composite is from about 0.036% by weight to about 0.21% by weight. 7 . The magnetic composite according to claim 3 , wherein the percentage by weight of bismuth oxide to the whole magnetic composite is from about 0.036% by weight to about 0.21% by weight. 8 . The magnetic composite according to claim 4 , wherein the percentage by weight of bismuth oxide to the whole magnetic composite is from about 0.036% by weight to about 0.21% by weight.
