PROCESS FOR OBTAINING A THIN, INSULATING, SOFT MAGNETIC FILM OF HIGH MAGNETIZATION, CORRESPONDING FILM AND CORRESPONDING INTEGRATED CIRCUIT

摘要

A thin soft magnetic film combines a high magnetization with an insulating character. The film is formed by nitriding Fe-rich ferromagnetic nanograins immersed in an amorphous substrate. A selective oxidation of the amorphous substrate is then performed. The result is a thin, insulating, soft magnetic film of high magnetization. Many types of integrated circuits can be made which include a component using a membrane incorporating the above-mentioned thin film.
