Abstract
Cox Fea-xO4 (0. 1≤×≤1.0) films and a Co0.1Fe2.9 O4/Zn0.5Fe2.5O4 double layered film were prepared on soda-lime glass substrate (a=87×10-7/deg) by plasma enhanced MOCVD and their microstructures and magnetic properties were studied. The Co ferrite films consisted of a random orientated initial layer (thickness orientated columnar layer. Conversion electron Mossbauer spectra and magnetization curves of the films indicated that the films had an easy axis perpendicular to the film plane. The Co ferrite film with higly perpendicular magnetic anisotropy could be obtained by using Zn ferrite film (thickness:210 nm) as a buffer layer between the Co ferrite film and the substrate.
