摘要：

The crystal structures and electric properties of epitaxial (1 - x)BiFeO3-xBiCoO(3) thin films with x 0{0: 30 prepared by chemical solution deposition on SrTiO3(001) and SrRuO3(001)/SrTiO3(001) substrates were investigated. The crystal structures changed from rhombohedral to tetragonal at x = 0.15-0.2. Saturated ferroelectric polarizations were observed for films with x = 0-0.10, and films with x = 0.15-0.20 did not show polarization reversal. The piezoelectric constant d(33) initially increased with increasing Co content and showed a maximum value of 80 pm/V at x = 0.05. (C) 2010 The Japan Society of Applied Physics
