Relation between Fractal Inhomogeneity and In/Nb-Arrangement in Pb(InNb)O.

Relaxor ferroelectrics show substantial responses to electric fields. The key difference from normal ferroelectrics is a temperature-dependent inhomogeneous structure and its dynamics. The lead-based complex perovskite Pb(InNb)O is an intriguing system in which the inhomogeneous structure can be controlled by thermal treatment.

Interpretation of T(m) and T* in relaxor ferroelectric 0.93Pb(Zn₁/₃Nb₂/₃)O₃-0.07PbTiO₃.

The dielectric property of relaxor ferroelectric 0.93Pb(Zn₁/₃Nb₂/₃)O₃-0.07PbTiO₃ single crystals (PZN-0.

Dynamical properties of the relaxor ferroelectric 0.71Pb(Ni1/3Nb2/3))O3-O.29PbTiO3 probed by Brillouin and Raman scattering.

Abstract-Structural phase transitions in relaxor ferroelectric materials remain to be one of the most puzzling issues in materials science. In the present work, we have investigated relaxational and vibrational properties of a relaxor ferroelectric 0.71Pb(Ni(1/3)Nb(2/3))O(3)-O.

Raman scattering study of Ca-modified lead titanate.

The paraelectric to ferroelectric phase transitions were studied by Raman scattering in Ca-doped lead titanate ceramics. The soft optic modes responsible for the ferroelectric phase transitions were clearly observed. The A(1)(1TO) mode, which softens toward T(c), contains four subpeaks.
