  • Relaxor ferroelectrics are a prototypical example of ferroic systems in which interplay between atomic disorder and order parameters gives rise to emergence of unusual properties, including non-exponential relaxations, memory effects, polarization rotations, and broad spectrum of bias- and temperatureinduced phase transitions. Despite more than 40 years of extensive research following the original discovery of ferroelectric relaxors by the Smolensky group, the most basic aspect of these materials the existence and nature of order parameter has not been understood thoroughly. Using extensive imaging and spectroscopic studies by variable-temperature and time resolved piezoresponse force microscopy, we fi nd that the observed mesoscopicmore » behavior is consistent with the presence of two effective order parameters describing dynamic and static parts of polarization, respectively. The static component gives rise to rich spatially ordered systems on the 100 nm length scales, and are only weakly responsive to electric fi eld. The surface of relaxors undergoes a mesoscopic symmetry breaking leading to the freezing of polarization fl uctuations and shift of corresponding transition temperature.« less
  • Changes in the electrostrictive coefficients Q{sub ij}, especially the volumetric coefficient, with temperature and bias field provides important information regarding the nature of the polarization in lead magnesium niobate based relaxor ferroelectrics. We show that the polarization response at temperatures near the dielectric constant maximum is mainly through the polar-vector reorientation of the nanopolar regions, as suggested by the polar glass model. As the temperature is lowered through the freezing transition, the polarization response is governed by the phase switching and intrinsic contributions rather than by the domain wall motions found in normal ferroelectrics. {copyright} {ital 1997 American Institute ofmore » Physics.}« less
  • The complex structure of relaxor ferroelectrics comprises polar nanoregions (PNRs) which appear upon cooling below the Burns temperature and quenched compositional (chemical) disorder. The relation between the polar nanostructure and compositionally ordered regions (CORs) often observed in relaxors has been the subject of extensive theoretical investigations; however, the experimental data, especially concerning Pb(B0 1=3B00 2=3)O3-type complex perovskite relaxors, are rather limited. In this paper, we analyse and discuss the results of our recent investigations of the morphology of CORs and the dynamics of PNRs in Pb(Mg1/3Nb2/3)O3-based solid solutions in which the degree of compositional disorder was varied by means ofmore » changing the composition and/or by means of high-temperature annealing. The samples were characterised using X-ray diffraction, transmission electron microscopy, piezoresponse force microscopy, Brillouin light scattering, dielectric spectroscopy, as well as by measuring pyroelectric effect and ferroelectric hysteresis loops. No influence of the size of CORs on the PNRs relaxation in the ergodic relaxor phase is found. Instead, the CORs size influences significantly the diffuseness of the transition from the field-induced ferroelectric phase to the ergodic relaxor state. The results are interpreted in the framework of a model suggesting the coexistence of static and dynamic PNRs in the ergodic relaxor phase.« less
  • A thermally stable double beam laser interferometer for the measurement of mechanical strains due to domain switching in ferroelectric materials is described. Sample sizes vary from 0.25 mm to 5 mm in thickness, and maximum strains produce from 1 to 50 fringes in the data. A quadrature detection scheme provides the resolution which is required to interpolate accurately the fringe record and determine the direction of surface mechanical displacement. Specific sample mounting techniques are also developed in order to attain well-defined loading conditions. Two sample holders, one for mounting very thin discs and the other for 5 mm cubes, aremore » described. They induce minimal mechanical loadings on the samples. Typical data exhibiting the effects of domain switching due to an applied electric field are shown for the hot-pressed ceramic PZT 65/35.« less
