Polarization of Surface Layers in PLZT Relaxor Ceramics

The possibility of inducing a polarization state in PLZT-10 relaxor ceramics under exposure to external electric fields and intensive light illumination at room temperature was shown in this paper. Such polarization state was studied by a dynamic method of investigating pyroelectric properties. It was established that a fairly stable polarization state can also be created in PLZT-10 ceramics when studying it by means of the piezoelectric force microscopy. In the latter case, hysteresis loops of a local piezoelectric response have been obtained.
