“…In general, it is known that Raman spectra of these materials change only slightly at ferroelectric phase transitions. In fact, the positions and shapes of the principal Raman bands in our experiments were very similar to those reported in previous investigations of PMNxPT with a comparable composition [15][16][17][18][19][20][21][22][23] . Fortunately, at least the relative intensities of Raman spectra taken in dark and light stripes are different.…”

The paper describes heterostructures spontaneously formed in (1-x)Pb(Mg 1/3 Nb 2/3 )O3-xPbTiO3 (PMN-xPT) single crystals cooled under bias electric field applied along [001]pc and then zero-fieldheated in the vicinity of the so-called depoling temperature TRT. In particular, formation of lamellar structures composed of tetragonal-like and rhombohedral-like layers extending over macroscopic (mm) lengths is demonstrated by optical observations and polarized Raman investigations.

“…The films with x = 0 and 0.85 have typical spectra of cubic ͑Fm3m͒ and tetragonal symmetries, respectively, and the shapes of the peaks are in good agreement with the data reported for sintered bodies and single crystals. [21][22][23] The Raman peak of the film with x = 0.42, on the other hand, shows mixed spectra of cubic and tetragonal symmetries. This composition corresponds to the mixed phase of pseudocubic ͑rhombohedral͒ and tetragonal symmetries from the HRXRD-RSM results.…”

Relaxor-type ferroelectric ͑1−x͒Pb͑Mg 1/3 Nb 2/3 ͒O 3 -xPbTiO 3 ͑PMN-PT͒ films, 2 -3 m in thickness, with a PbTiO 3 content ͑x͒ ranging from 0 to 1 were grown on ͑100͒ c SrRuO 3 ʈ ͑100͒SrTiO 3 substrates at 650°C by metal-organic chemical vapor deposition. The effects the x value had on the crystal structure, dielectric and ferroelectric properties, and mechanical response of these films were systematically investigated. Epitaxial growth having ͑100͒ / ͑001͒ orientation irrespective of x and the constituent phase change with x were ascertained from both x-ray diffraction reciprocal space mapping analysis and Raman spectroscopy. The constituent phase changed from a rhombohedral ͑pseudocubic͒ single phase, a mixture phase of rhombohedral ͑pseudocubic͒ and tetragonal phases, and a tetragonal single phase, with increasing x. The mixed phase region was found to exist at x = 0.40-0.55, which was different from that reported for single crystals ͑x = 0.31-0.35͒. The dependencies of relative dielectric constant and remanent polarization on x showed a similar trend in the case of a PMN-PT sintered body; however, the magnitudes of these values were relatively low. The effective longitudinal piezoelectric coefficient ͑d 33,f ͒ and the transverse coefficient ͑e 31,f ͒ of 100-120 pm/ V and ϳ−11.0 C / m 2 were, respectively, calculated for a film with x = 0.39, which corresponds to a larger x edge for the rhombohedral ͑pseudocubic͒ region following the engineered domain concept proposed for PMN-PT single crystals.

“…Low wavenumber region (100 -250 cm -1 ) chiefly involves cationic network and the lattice modes while a 250 to 800 cm -1 spectral range reveals the bending and stretching modes of the covalent-bonded octahedron [3,33]. Figure 7 are typical for relaxor ferroelectrics [3,17,18,[33][34][35][36][37]. They consist of a number of broad bands observed in the whole measured temperature range, even within the paraelectric cubic phase with the Pm3m space group.…”
