Abstract
Local control of the growth‐induced anisotropy in LPE bubble garnet films can be obtained by masking part of the film with a layer of epitaxial Gd3Ga5O12 and annealing at elevated temperatures (∼ 1200 °C) in a nitrogen atmosphere for approximately 1 h. In the regions exposed to nitrogen, the introduction of oxygen vacancies accelerates the reduction of Ku by the randomizing of the rare‐earth ion distribution.Keywords
