Abstract
Magnetic bubble domains have been found in rare earth intermetallic systems with GdCo alloys, as an example. Films prepared by sputtering are found to be amorphous with perpendicular anisotropy. The GdCo system will support magnetic domains in a wide variety of compositions and the magnetic bubble domains are readily varied in diameter. The use of these amorphous systems is shown to be substrate independent. The amorphous magnetic system is described and domain size variations with film composition are shown. These materials are also useful magneto-optic materials with excellent signal to noise characteristics.
