ABSTRACT
Ferroelectric hysteresis at approximately 20°C is measured in a lead zirconate titanate film prepared by stacking monodisperse and perovskite particles 9 nm in diameter. The particle-stacked film possesses a remanent polarization of 4.5 μC/cm2 and an apparent coercive field of 250 kV/cm. This result demonstrates that particulate lead zirconate titanate of 9 nm in diameter retains ferroelectricity even at room temperature.
