Sol-gel derived YMnO3 films have been prepared on platinized Si wafers. Crystallization took place at firing temperatures above about 750 C. The crystallized films were very conductive. YMnO3 films exhibited a dielectric constant of 23, a remanent polarization of 1.0 μC/cm2 and a coercive field of 12 kV/cm, all measured at -33 C. The FE loop was lossy and elliptical at room temperature but became more distinct at lower measuring temperatures or at higher measuring frequencies.
