Abstract
Abstract Barium titanate (BaTiO 3 , BT)–bismuth titanate magnesium oxide (Bi(Mg 1/2 Ti 1/2 )O 3 , BMT)–bismuth ferrite (BiFeO 3 , BF) solid solution ceramics were prepared using a conventional solid-state synthesis, and their piezoelectric properties and microstructure were investigated. X-ray diffraction (XRD) patterns revealed the single phase of perovskite oxide for 0.3BT–0.1BMT–0.6BF ceramics. Strain–electric field curves of the sample with 0.3BT–0.1BMT–0.6BF exhibit ferroelectric butterfly-like curves. A strain maximum/electric field maximum ( S max / E max ) was 330 pm/V. Transmission electron microscopy revealed dot-like domains(Nanodomains) inside the ferroelectric domain structures in the 0.3BT–0.1BMT–0.6BF.
