Title:
Y型六方晶系フェライト薄膜およびその製造方法
Document Type and Number:
Japanese Patent JP4068297
Kind Code:
B2
Abstract:
The present invention provides a Y-type hexagonal ferrite thin film suitable for high frequency devices, having a crystal structure with the c-axis oriented perpendicular to the surface of the thin film. The present invention also provides a method of producing the Y-type hexagonal ferrite thin film, comprising the steps of preparing a viscous solution containing a metal-organic complex which is formed using a primary component including a Fe <+3> ion, and a secondary component including a Ba <2+> ion, at least one transition metal ion selected from the group consisting of Fe <2+>, Co <2+>, Ni <2+>, Zn <2+>, Cu <2+> and Mn <2+>; and optionally at least one metal ion selected from the group consisting of Sr<2+>, Ca <2+> and Pb <2+>, forming a film having a Y-type ferrite composition on a surface made of noble metal through a coating process using the viscous solution, and burning the film at a temperature of 750 DEG C or more.
