Epitaxial stabilization of hexagonal RMnO3 (R = Eu-Dy) manganites

Epitaxial thin films of RMnO3 (R = Sm, Eu, Gd, Dy) have been prepared using liquid injection MOCVD. The formation of a high-temperature hexagonal modification for DyMnO3 and bulk hexagonal EuMnO3 and GdMnO3, which does not exist for the bulk compounds, has been observed on ZrO2 (Y2O3) (111) substrates at 900 degreesC due to epitaxial stabilization.
