Abstract
Electric fields of different nature induced in lanthanum doped lead zirconate-titanate (PLZT) ceramics were studied by confocal Raman microscopy. Temperature dependence of the pyroelectric field was determined and the value of pyroelectric coefficient was estimated. An appearance of additional line in Raman spectrum of PLZT after e-beam irradiation was revealed and its spatial distribution was studied. The origin of this spectral line was discussed in terms of defects formation and phase transitions.
