ABSTRACT:
A process for producing an ion implanted bubble device having bubble propagation tracks formed by implanting ions in a magnetic layer formed on a substrate. The process includes: implanting ions in the magnetic layer for forming a desirable bubble propagation track thereon; exposing the ion implanted magnetic layer to plasma in order to enhance the anisotropy field change .DELTA.Hk; coating an intermediate insulation film over the magnetic layer treated with plasma; and forming bubble propagation patterns of ferromagnetic material and/or conductor patterns of conductive material on the intermediate insulation film.
