Thin films of a rhombohedral-tetragonal solid solution (1 - x)BiFeO3-xBiCoO(3) with x = 0-0.30 were prepared by chemical solution deposition on LaAlO3(001) and (La-0.5,Sr-0.5)CoO3(001)/LaAlO3(001) substrates. A BiCoO3-type tetragonal structure with a large c/a of 1.23 was grown adjacent to the substrate whereas a BiFeO3-type rhombohedral one was grown on the tetragonal phase. Co substitution in the rhombohedral phase led to enhancement of piezoelectric constant and d(33) reached 100 pm/V, almost double that of BiFeO3. (C) 2011 The Japan Society of Applied Physics
