There has been a lot of interest on ferroelectric (FX) films especially for non-volatile memories and ultra high density DRAM applications. These films such as PZT and (Ba,Sr)Ti03 are crystalline perovskite.BiFeO3 is an interesting antiferromagnetic material which belongs to the perovskite crystal structure. Sol-gel derived BiFe03 films have been prepared on platinized Si substrates and their electrical arid magnetic properties were obtained. XRD indicated that the films were crystalline perovskite when fired at 400°C and above. Dielectric constant of up to 100 was also obtained; however, the films tend to exhibit low resistivities especially in films fired to higher temperatures. The hysteretic loops obtained indicated a remanent polarization and coercive field of 5.5 pC/cm2 and 180 kV/cm respectively.
