Abstract: The reversal of the crystal lattice during the formation of spherolite islands in thin films of lead zirconate-titanate is studied using scanning electron microscopy by diffraction of reflected electrons. It is shown that the lattice reversal in spherulites can occur both towards the center of the spherulite and towards its periphery. The mechanisms of formation and growth of spherulites are considered to explain the observed effect.

Keywords: thin films of lead zirconate, CTS, rotational crystals, spherulite microstructure, reversal mechanisms.
