The effect of substrate orientation on the growth kinetics of garnet liquid phase epitaxy

The growth kinetics of liquid-phase epitaxy of Y3Fe5O12 on Gd3Ga5O12 substrates having (110), (211), (321), (100) or (111) orientation has been studied and the results are discussed in terms of simple theoretical growth models. The (111) face is a rough face on an atomic scale, but the other faces are more or less singular faces. Growth hillocks are observed on the surfaces of films grown on (110), (211) and (321) substrates. The epitaxial layer...
