“…These incidence directions are found corresponding to the (0 0 L) peaks of the perovskite PZNT and STO, so it is evident that the LPE film has a regular epitaxial orientation with (0 0 1) PZNT //(0 0 1) STO . The XRD peak of PZNT {0 0 2} is found to be very close to the STO {0 0 2} peak, which is consistent with the similar lattice constants between them [9,10]. Further investigation on the orientation relationship has been performed by Xray diffraction pole patterns.…”

The structure and the dielectric properties of Pb(Zn 1/3 Nb 2/3 )O 3 (PZN) crystal have been investigated by means of high-resolution synchrotron xray diffraction (with an x-ray energy of 32 keV) and dielectric spectroscopy (in the frequency range 100 Hz-1 MHz). At high temperatures, the PZN crystal exhibits a cubic symmetry and polar nanoregions inherent to relaxor ferroelectrics are present, as evidenced by the single (222) Bragg peak and by the noticeable tails at the base of the peak. At low temperatures, in addition to the well-known rhombohedral phase, another low-symmetry, probably monoclinic, phase is found. The two phases coexist in the form of mesoscopic domains. The ferroelectric phase transition is diffuse and observed between 325 and 390 K, where the concentration of the low-temperature phases gradually increases and the cubic phase disappears upon cooling. However, no dielectric anomalies can be detected in the temperature range of the diffuse phase transition. The temperature dependence of the dielectric constant shows a maximum at higher temperature (T m = 417-429 K, depending on frequency) with the typical relaxor dispersion at T < T m and the frequency dependence of T m fitted to the Vogel-Fulcher relation. Application of an electric field upon cooling from the cubic phase or poling the crystal in the ferroelectric phase gives rise to a sharp anomaly of the dielectric constant at T ≈ 390 K and greatly diminishes the dispersion at lower temperatures, but the dielectric relaxation process around T m remains qualitatively unchanged. The results are discussed in the framework of the present models of relaxors and in comparison with the prototypical relaxor ferroelectric Pb(Mg 1/3 Nb 2/3 )O 3 .

The relaxors Pb(Zn 1/3 Nb 2/3 )O3 (PZN) and Pb(Mg 1/3 Nb 2/3 )O3 (PMN) have very similar properties based on the dielectric response around the critical temperature Tc (defined by the structural transition under the application of an electric field). It has been widely believed that these materials are quite different below Tc with the unit cell of PMN remaining cubic while in PZN the low temperature unit cell is rhombohedral in shape. However, this has been clarified by recent highenergy x-ray studies which have shown that PZN is rhombohedral only in the skin while the shape of the unit cell in the bulk is nearly cubic. In this study we have performed both neutron elastic and inelastic scattering to show that the temperature dependence of both the diffuse and phonon scattering in PZN and PMN is very similar. Both compounds show a nearly identical recovery of the soft optic mode and a broadening of the acoustic mode below Tc. The diffuse scattering in PZN is suggestive of an onset at the high temperature Burns temperature similar to that in PMN. In contrast to PMN, we observe a broadening of the Bragg peaks in both the longitudinal and transverse directions below Tc. We reconcile this additional broadening, not observed in PMN, in terms of structural inhomogeneity in PZN. Based on the strong similarities between PMN and PZN, we suggest that both materials belong to the same universality class and discuss the relaxor transition in terms of the three-dimensional Heisenberg model with cubic anisotropy in a random field.
