Abstract

We have studied the crystal growth behavior of multiferroic YMnO3films synthesized by pulsed laser deposition on several different substrates. The growth orientation and surface morphology of YMnO3films were sensitively dependent on the substrates and deposition conditions. An excellent epitaxial hexagonal YMnO3film was grown on the (111) Y-stabilized ZrO2substrate, but with increasing the oxygen pressure few percentage of 30° twin growth was developed. On the other hand, the YMnO3film on the Si substrate with an amorphous SiO2layer exhibited (0001) or (112̄1) orientation. The (0001) oriented hexagonal YMnO3phase was a stable one under tensile stress by the (0001) Al2O3substrate, while it competed with the (011)-oriented orthorhombic YMnO3phase under the compressive stress by the (111) SrTiO3substrate.
