[Display omitted] • Y 3 Fe 5 O 12 -BaFe 12 O 19 nanocomposite film was deposited on Al 2 O 3 substrate. • High exchange spring coupling was observed between the two films. • The nanocomposite film has a high remanence ratio of 0.65. Preparation of a high remanence ratio of M-type barium ferrite film is highly desirable in self-biased microwave devices. In this letter, Y 3 Fe 5 O 12 -BaFe 12 O 19 nanocomposite film with a high remanence ratio was deposited on the Al 2 O 3 substrate. Multiple crystal structure characterizations confirm that the Y 3 Fe 5 O 12 film was grown on the orientation BaFe 12 O 19 film surface with high crystallinity and low roughness. The magnetism measurement displays that the nanocomposite film has a high remanence ratio of 0.65 for its high exchange spring coupling. Consequently, this work gives an approach to preparing ferrite film with a high remanence ratio which is applied in self-biased devices. [ABSTRACT FROM AUTHOR]
