In this review the dielectric properties of relaxor ferroelectrics are discussed and compared
with the properties of normal dielectrics and ferroelectrics. We try to draw a general picture of …

Spatial variability of polarization relaxation kinetics in the relaxor ferroelectric 0.9 Pb (Mg 1/3
Nb 2/3) O 3-0.1 PbTiO 3 is studied using time-resolved piezoresponse force microscopy at …

The complex structure of relaxor ferroelectrics comprises polar nanoregions (PNRs) which
appear upon cooling below the Burns temperature and quenched compositional (chemical) …

The colossal piezoelectric effect of relaxor-based ferroelectrics has attracted much attention

Ternary solid solution crystals of 0.19 Pb (In 1/2 Nb 1/2) O 3− 0.46 Pb (Mg 1/3 Nb 2/3) O 3−
0.35 PbTiO 3 [PIMNT (19/46/35)] with dimensions of 35× 38× 15 mm 3 were grown by the …

The 1: 1 B-site cation order in Pb (Mg 1/3 Nb 2/3) O 3 relaxor ferroelectric ceramics was
significantly enhanced by doping of minor amounts of La 3+, Sc 3+, or W 6+(less than 3 …

The electrostriction effect is widely present in insulators and dielectrics as a secondary effect
of the electric fields. It offers distinct advantages over the strain caused by piezoelectric …

Hypersonic elastic anomalies are investigated in ferroelectrics with perovskite structure by
micro-Brillouin scattering to make clear the role of polar nanoregions (PNRs) and static …

PbMg 1/3 Nb 2/3 O 3 (PMN) is a well known ferroelectric relaxor. PMN crystal doped with La
