ABSTRACT:
A paste for manufacturing ferrite is produced by dissolving the following materials: organometallic compound comprising a metal element Fe (A); organometallic compound comprising a metal element Me (Me herein denotes at least one element selected from the group consisting of Mn, Li, Mg, Ni, Zn, Y and Gd) (B); and at least one material selected from terpenoid carboxylic acid and resins containing the composition of the terpenoid carboxylic acid (C) in organic solvent (D). The paste permits providing a dense and homogeneous ferrite with a good property. Moreover, the use of such ferrite permits producing ferrite thin films. Furthermore, the ferrite with an excellent high-frequency property can be provided by coating and firing the paste of the present invention. The temperature properties of YIG thin film and Gd-substituted YIG thin film of the present invention are shown.
