摘要

Neodymium-modified Bi_4Ti_3O_(12)(BNdT) thin films have been prepared by pulsed laser deposition (PLD), aiming to realize enhanced ferroelectric properties by a low temperature treatment. When deposited at 500℃, the film shows P-E hysteresis having twice remanent polarization 2P_r of 78.8 μC/cm~2, coercive force Ec of about 250 kV/cm, and leakage current of less than 10~(-7) A/cm~2 from -50 to +50 kV/cm. Good fatigue properties of BNdT films deposited at 5 Hz have been obtained up to 10~(10) cycles of 500 kHz bipolar square pulses, with less than 25% decrease of +P_r and -P_r.
