Abstract
The suppressing of the switchable remnant polarization in PZT films at illumination in the external field is observed. This phenomenon is ex plained by the screening of the domain walls by the nonequilibrium car riers. The experimental results are compared with the switching kineti cs, suggested by Yshibashi and Takagi. The comparison reveals also the influence of the nonequilibrium carriers on the domain-wall velocity and nucleation rate.
