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+3ion, and a secondary component including a Ba2+ion, at least one transition metal ion selected from the group consisting of Fe2+, Co2+, Ni2+, Zn2+, Cu2+and Mn2+; and optionally at least one metal ion selected from the group consisting of Sr2+, Ca2+and Pb2+, 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° C. or more.
