Comments on Origins of Enhanced Piezoelectric Properties in Ferroelectrics

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2009
This review discusses recent advances in understanding origins of large piezoelectric properties in some ferroelectric materials. In particular, it addresses the role of polarization rotation and monoclinic phases. It is suggested that the polarization rotation is an old concept that was proposed more than 30 years ago to explain enhanced properties of

Dielectric properties of the ferroelectric ceramics

Journal of Physics D: Applied Physics, 1998
The temperature and frequency dependences of the permittivity , the dielectric loss factor and the resistance R of the ceramic Ti in the interval 100-800C were studied. A ferroelectric phase transition at temperature C was observed. Hysteresis loops typical for ceramic ferroelectrics were observed. Relaxation maxima of the dielectric loss factor in the

Ferroelectric properties of pyridinium perrhenate

The Journal of Chemical Physics, 1997
Polycrystalline pyridinium perrhenate has been studied over a wide range of temperatures by differential thermal analysis, differential scanning calorimetry, proton NMR spectra and relaxation, and dielectric permittivity measurements. Two solid–solid phase transitions at 250 and 333 K have been revealed and the pyridinium cation reorientations ...

Properties of new ferroelectric materials

Liquid Crystals, 1989
Abstract A homologous series of chiral 4-(3-methylpentyl)benzenethio-4′-n-alkoxy-benzoates has been studied. These thioesters display a ferroelectric, chiral smectic C phase in addition to cholesteric and smectic A phases. A comparison is made between the thioester series and a phenylbenzoate, having the same molecular end group.
