Growth of uniaxial magnetic garnet films by rf sputtering

Epitaxial films of gadolinium-gallium-substituted yttrium iron garnet (Gd: Ga: YIG) films have been grown by rf-sputtering techniques on 〈111〉 gadolinium gallium garnet (GGG) substrates. The as-deposited films were annealed to yield crack-free epitaxial garnets, which exhibited movable magnetic (bubble) domains. Typical magnetic data for the sputtered Gd: Ga: YIG films are presented. © 1972 The American Institute of Physics.
