Abstract
The Electric Scanning Force Microscope is used to investigate the poli ng behaviour of ferroelectric PZT thin films. Successively measured po larization distributions were compared with high resolution. The polin g characteristics are investigated separately at the grain boundaries and inside the grain volumes. For films prepared by sol-gel processing , it is shown that the switchable polarization is decreased at the gra in boundaries with respect to the grain volumes. The coercive field is clearly increased at the grain boundaries.
