ABSTRACT:
A method of fabricating a magnetic bubble memory device is disclosed in which ions are implanted in a desired portion of a surface region in a magnetic bubble film for magnetic bubbles to form a strain layer having a strain of about 1% to about 2.5%, a film is provided on the magnetic bubble film so as to cover the magnetic bubble film with the film and then the magnetic bubble film is annealed under predetermined conditions, thereby providing a practical magnetic bubble memory device having a large bias margin.
