Abstract
A scanning force microscope (SFM) with light fiber sensor was construc ted. The SFM operates in the repulsive contact mode. Three pictures ha ve been measured simultaneously: the topography and the 1st and 2nd ha rmonic. The 1st harmonic can be related to piezoelectricity and polari zation. The 2nd harmonic is correlated with electrostriction and permi ttivity. The conductive tip of the SFM was used to polarize lead zirco nate titanate (PZT) films and to image their domain structure on a nan ometer scale. In addition, a writing experiment has been performed.
