Ferroelectric (FE) thin-film capacitors were irradiated to 100 Mrad(Si) with 10-keV x-rays. Some of the FE hysteresis loops show distortion at 5 Mrad(Si). The type and degree of distortion is dependent upon the polarization state and/or the applied field during irradiation. Preliminary results indicate that a fraction of the radiation-induced damage can be removed simply by cycling the FE capacitor with a 20-Khz square wave. The amount of damage removed is dependent upon the radiation conditions.
