X-ray studies of the crystal structure in Pb[sub 1-x](Li[sub 1/2]La[sub 1/2])[sub x]Zr[sub 1-y]Ti[sub y]O[sub 3] solid solutions at the phase transition from a paraelectric state into ordered states near the triple ferroelectric–antiferroelectric–paraelectric point of the “Ti-content–temperature” phase diagram are carried out. Analysis of the shape of characteristic x-ray lines indicates the presence of two-phase nuclei with ferroelectric and antiferroelectric types of dipole ordering in the crystal lattice of the solid solutions above the point of the paraelectric phase transition (the Curie temperature). © 2001 American Institute of Physics.
