Abstract
Renormalization phenomena in the palmierite-type compound lead phospha te are a consequence of order parameter coupling with defect induced c onjugated fields. The influence of the lead dilution by barium and str ontium on the improper ferroelastic transformation, the plateau effect and the ferroelastic domain pattern is studied. The critical behaviou r of the diluted three states Potts system with the order parameter co mponents {Q(1.3)} was determined by Raman spectroscopy, optical birefr ingence and X-ray diffraction,.
