Abstract:

A magnetic bubble domain structure and method of making comprising a film of a nickel-iron alloy of 80 to 83.5 nickel content and substantially zero constant of magnetostriction formed by vapor deposition of the alloy onto a flat substrate at a substrate temperature in the range of room temperature to 200 degree C. at an angle of incidence of approximately 60 degree to a film thickness of 0.2 microm to 3.0 microm, the film being immersed in a magnetic field perpendicular to the film and of 1600 to 2400 oersteds intensity.
