PROBLEM TO BE SOLVED: To develop a means of producing a Y type hexagonal crystal system ferrite thin film for high frequency. SOLUTION: The Y type hexagonal crystal system ferrite thin film with a C axis of the crystal oriented vertically to a film face is produced by the following step: forming a Y type ferrite composition film on the surface of a precious metal with coating method by the use of a viscous solution comprising a metal and organic complex which is formed by having as a main component Fe+3 ion and as a subcomponent at least one transition metal ion selected from the group consisting of Fe2+, Co2+, Ni2+, Zn2+, Cu2+ or Mn2+, and Ba2+, or at least one metal ion selected from the group consisting of Sr2+, Ca2+ or Pb2+, and thereafter sintering the Y type ferrite composition film at >=750 deg.C. |
