Abstract

The effect of light doping on the phase transition to the ferroelec. state in BaTiO3 was studied using synchrotron radiation at Daresbury Lab., UK. The presence of dil. impurities, which turn BaTiO3 from a wide band-gap intrinsic semiconductor into an extrinsic n-type semiconductor, change the transition from a discontinuous to a continuous one, and produce large spatial variation in magnitude of the elec. polarization in both the high- and low-temp. phases; these fluctuations were barely detectable in the pure, annealed material.
