Nanocrystalline Ferroelectric/Relaxor Multilayers
Ferroelectrics, 2002After investigations on sputtered nanocrystalline ferroelectric Pb 0.76 Ca 0.24 TiO 3 (PTC) films and nanocrystalline relaxor films, namely Pb(Sc 0.5 Ta 0.5 )O 3 (PST), Pb(Sc 0.5 Nb 0.5 )O 3 (PSN) and Pb(Mg 1/3 Nb 2/3 )O 3 (PMN) we started to investigate effects in multilayers of nanocrystalline ferroelectric and relaxor films.

Phases in relaxor ferroelectric crystals
ISAF 2000. Proceedings of the 2000 12th IEEE International Symposium on Applications of Ferroelectrics (IEEE Cat. No.00CH37076), 2002The dielectric permittivity and domain structures have been measured as a function of temperature in relaxor ferroelectric single crystals (PbMg/sub 1/3/Nb/sub 2/3/O/sub 3/)/sub 1-x/(PbTiO/sub 3/)/sub x/ (PMN-xPT) for x=0.31 and 0.34. Both PMN-31%PT and PMN-34%PT crystals show complex dielectric and domain configurations with coexistence of trigonal ...

The dielectric behavior of relaxor ferroelectrics
Ferroelectrics, 2001Abstract A simple relationship describing temperature and frequency dependence of dielectric constant in relaxor ferroelectrics is derived from a distribution model of relaxation times, and found to be in good agreement with experimental results. We discuss the physical meaning of the activation energy E in the relaxor ferroelectrics, when the dipolar ...

Polarization anomalies in a relaxor ferroelectric
Journal of Experimental and Theoretical Physics Letters, 2000With a strontium barium niobate crystal used as an example, it is experimentally demonstrated that relaxor ferroelectrics exhibit pronounced polarization anomalies, which manifest themselves in the difference between the trajectories of the dielectric hysteresis observed in several repeated cycles of a varying external electric field.

Glassy Phenomena in Relaxor Ferroelectrics
2014Quenched random fields (RFs) are widely believed to be at the origin of the peculiar behavior of relaxor ferroelectrics such as PbMg1/3Nb2/3O3 (PMN), SrxBa1-xNb2O6 (SBN), and BaTi1−x Zr x O3 (BTZ), hence, giving rise to strong frequency dispersion of the dielectric response, an apparent lack of macroscopic symmetry breaking at low temperatures, and the

Giant electrostrictive effects of NaNbO3-BaTiO3 lead-free relaxor ferroelectrics
, 2016A giant electrostrictive effect was observed in (1 − x)NaNbO3-xBaTiO3 relaxor ferroelectric ceramics, which exhibit a high electrostrictive coefficient Q33 of ∼0.046 m4/C2 twice as large as those of Pb- and Bi-based perovskite relaxor ferroelectric ...

Relaxor ferroelectric-based ceramics
2010Ferroelectric relaxor characteristics are discussed in conjunction with the disordered arrangement of the constituent ions. Dielectric properties are characterized by giant and temperature-insensitive dielectric constants and large frequency dependence (referred to as “dielectric relaxation”).
