| 简介 |
PROBLEM TO BE SOLVED : To obtain a magnetic material capable of firing at a low temp. and useful to obtain a small-sized high-frequency inductor element ensuring a high inductance value or a high-frequency irreversible circuit element ensuring a small insertion loss by using a phase having a specified garnet structure as a principal component. SOLUTION : The principal compsn. of this magnetic material is based on a phase having a garnet structure represented by the formula Y3-x-y Bix Ry Fe5 O12 (where R is one or more kinds of rare earth metals selected from among La, Nd, Sm, Eu, Gd, Tb and Dy, 0
