Annealing-Induced Relief of Compressive Misfit Strain in Liquid Phase Epitaxial Yttrium Iron Garnet Films.

摘要

Films of yttrium iron garnet were grown on (111) gadolinium gallium garnet by liquid phase epitaxy from a PbO-B2O3 flux. Incorporation of Pb as a substitutional impurity produced an increase in film lattice parameter which resulted in initial compressive misfit strains in the films.
