Calcium germanium substituted iron garnet films for magnetic bubble applications

Abstract

Mixed rare earth iron garnet films containing calcium and germanium have been grown on (111) oriented gadolinium gallium garnet (GGG) substrates. The effect of growth conditions on film composition and properties is discussed. The 5 μm diameter bubble films have good magnetic properties; however, temperature control during film growth is very critical. © 1975 Chapman and Hall Ltd.
