Abstract

The ferroelectric and piezoelectric properties of (001) BiScO ₃-PbTiO₃ epitaxial films were investigated. Epitaxial films 1 μm thick were grown by pulsed laser deposition using ceramic targets of (1-x)BiScO₃-xPbTiO₃ (x=0.5) at substrate temperatures of 700°C on (100) SrRuO₃/(100)LaAlO₃ substrates. Well-saturated hysteresis loops with a remanent polarization of 36 μC/cm ² were observed. The films had a room temperature dielectric constant of 800, tanδ=0.09 and a maximum permittivity of 3600 at 460°C. The room temperature e_31f piezoelectric coefficient was -9 C/m ². The piezoelectric properties obtained were comparable to those of Pb(Zr,Ti)O₃ or relaxor ferroelectric-PbTiO₃ films.
