Abstract
Garnet films of compositions (EuLaCa)3 (FeGeAl)5O12 which support magnetic bubbles have been grown by liquid phase epitaxy on (110), (111), and (100) substrates of Nd3Ga5O12. In each material, La plus Eu provides the growth‐induced uniaxial anisotropy in (100) films, Ca plus Eu in (111) films, and the combination provides a normal easy axis as well as in‐plane anisotropy in (110) films. General conditions for achieving stable bubbles and large in‐plane anisotropy in (110) films are discussed in terms of the phenomenological theory of growth‐induced plus stress‐induced anisotropy.Keywords
