We report on the transport properties of and films. The samples show metallic transport and several samples exhibit a hysteretic drop of resistance during cooldown at The ferroelectric samples, grown in capacitor structures, have nonlinear, diode-like and hysteretic characteristics. Two charge-controlled transport regimes are found, which can be utilized for switching the devices between two voltage states.
