“…The XPS results obtained by Parmigniani et al [29] exhibit a random distribution of Nb and Mg ions on the cationic site. An excess of lead was observed in PT by Leinen et al [35] and by Preston et al [36]. They conclude that this excess really improved the quality of crystals.…”

The (1− x)PbMg1/3Nb2/3O3–xPbTiO3 ((1− x)PMN –xPT) single crystals with x equal to 0, 0.22, 0.28, 0.32, 0.37, 0.47, 0.69 and 1 were studied by x-ray diffraction and x-ray photoelectron spectroscopy. X-ray diffraction results reveal that with increase of Ti content the crystal symmetry changes from pseudo-cubic, characteristic for PbMg1/3Nb2/3O3 (PMN), to rhombohedral, then to monoclinic at the vicinity of the morphotropic phase boundary (MPB) region and finally to tetragonal, specific for PbTiO3 (PT). High-resolution core level spectra of the Pb 4f, O 1s, Nb 3d and Ti 2p states show that the bulk of the (1− x)PMN –xPT crystals, except PbTiO3 where Pb2+ and Pb4+ were detected, is characterized by only one chemical state for each element. However, in the case of the Pb and O spectra, apart from the main lines attributed to the lattice states, the satellite lines related to the surface states were also observed. The evolution of the lattice components of all core level spectra points to regular concentration dependence of the full width at half maximum (FWHM). With the rise of the Ti content the FWHMs increase and reach maxima for the MPB region, then decrease and achieve the smallest values for the pure PT. This characteristic FWHM behaviour points to disorder as an origin of the core level line broadening and it is discussed within the framework of the random field model. The FWHM of the Bragg’s reflections show similar concentration behaviour which confirms the existence of the highest structural disorder in (1− x)PMN –xPT system near the MPB.

“…It turned out that the spherulitic microstructure is widespread in thin polycrystalline films, including lead zirconate titanate (PZT) films (Alkoy et al 2007;Klee et al 1994;Preston, Haertling 1992;Pronin et al 2018), which are increasingly used in microelectromechanical and infrared technology devices (Izyumskaya et al 2007;Muralt et al 2009;Song et al 2021). However, there are practically no studies of the influence of the microstructure of films on their physical properties.…”

The paper shows that the formation of a radiant spherulites microstructure in lead zirconatetitanate thin films obtained by radio-frequency magnetron sputtering is associated with the formation of radial tensile mechanical stresses acting in the substrate plane, the magnitude of which increases with increasing linear size of spherulites. It leads to a change in the lattice parameter of the perovskite structure and the appearance of induced polarization, the value of which can significantly exceed the spontaneous polarization.
