ABSTRACT:
A polycrystalline film made of a ferromagnetic substance is deposited on a magnetic film to form a composite magnetic film. The composite magnetic film, unlike a conventional single-layered magnetic film made only of a Garnet film, is free from development of hard bubbles and has very excellent characteristics as magnetic film for use in a magnetic bubble device.
