Abstract :
Space charge distributions of PLZT 8/65/35 were measured by the laser intensity modulation method. The effect of space charge on the micro-macro domain transition is shown. Large differences in the depolarization temperature Td measured on heating and cooling are due mainly to the effect of space charge
