Cr-doped BiFeO 3 (BFO) thin films were formed by depositing sol–gel solutions on Pt/Ti/SiO 2 /Si(100) structures. Cr-doping up to 6 at % was effective in suppressing leakage current in the high electric field region and in increasing the remanent polarization. In a 3 at % Cr-doped 350-nm-thick BFO film, the remanent polarization as large as 100 µC/cm 2 and the coercive field of 260 kV/cm were observed when polarization vs electric field hysteresis loops were drawn at a frequency of 100 kHz with the maximum electric field of 750 kV/cm.
