Abstract

Thin films of BaCe_0.8Y_0.2O_3-δ (BCYO) and SrZr_0.8Y_0.2O_3-δ (SZYO) with a perovskite structure were deposited on (111)Pt//(111)SrTiO₃ (STO) single crystal substrates by an RF-magnetron sputtering method. X-ray diffraction revealed that the BCYO and SZYO thin films were polycrystalline but highly (110)-one-axis oriented with local epitaxy on (111)Pt//(111)STO in the 110-direction. However, these films have six-fold symmetric domains and each domain showed in-plane rotations because of the lattice mismatches between (110)BCYO or (110)SZYO and (111)Pt. Especially, the BCYO film showed larger in-plane rotation than that of SZYO because of its larger lattice mismatch.
