Evidences of a monoclinic phase in unpoled (PbMg 1/3 Nb 2/3 O 3) 1− x−(PbTiO 3) x with x=
0.35 (PMN-PT 35%) and unpoled (PbZn 1/3 Nb 2/3 O 3) 1− x−(PbTiO 3) x with x= 0.09 (PZN …

We have measured quantitatively the temperature dependence of the local distortions of
PbTiO 3 crystals below and above the structural ferroelectric phase transition, using x-ray …

We report a structural evolution analysis of the long-range and local order and disorder of
lead scandium niobate (PSN) down to 10 K, using a combination of neutron and x-ray …

Light scattering measurements are investigated as a function of temperature from 10 to 900
K in the tetragonal and cubic phases of a PbTiO 3 crystal. Phonon frequencies, ionic …

Single crystals of lead magnesium niobate, PbMg 1/3 Nb 2/3 O 3, were studied with x-ray
scattering measurements at temperatures between 10 and 350 K. The diffuse scattering …

This review covers methods and recent developments of the theoretical study of domain
structures in ultrathin ferroelectric films. The review begins with an introduction to some …

Currently, an intensive search for high-performance lead-free ferroelectric materials is taking
place. ABO3 perovskites (A= Ba, Bi, Ca, K and Na; B= Fe, Nb, Ti, and Zr) appear as …

Ferroelectric-paraelectric (FE-PE) phase transitions have been primarily explained by the
phenomenological Landau-Devonshire theory and a soft-zone-center mode of vibration in …

Synchrotron X-ray powder diffraction patterns were collected at the European Synchrotron
Radiation Facility (ESRF, Grenoble, France) on powder samples of PbTiO3 (tetragonal, Z= 1 …

Experimental information about the microscopic structure and the changes in this structure at
macroscopic phase transitions for the ferroelectric perovskites provide direct tests of …
