Growth of uniaxial magnetic garnet films by rf sputtering

Abstract
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.
