Phases in relaxor ferroelectric crystals

ISAF 2000. Proceedings of the 2000 12th IEEE International Symposium on Applications of Ferroelectrics (IEEE Cat. No.00CH37076), 2002
The 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 ...

Mixed systems of ferroelectric relaxors

Ferroelectrics, 2001
The random field based model for calculation of mixed systems of ferroelectric relaxors is proposed. Different orientations of electric dipoles related to different solid solution components and contribution of random field nonlinear and correlation effects were taken into account.

Relaxor ferroelectrics and intrinsic inhomogeneity

Europhysics Letters (EPL), 2005
Relaxor ferroelectrics (RF) are characterized by diffuse ferroelectric transitions and high and frequency-dependent dielectric susceptibilities. Non-RFs show high dielectric responses only in the direct vicinity of the transition temperature whereas RFs exhibit high responses over a large temperature range.

Phase Transitions in Relaxor Ferroelectricity

Ferroelectrics, 2007
Relaxors have a wide variety of industrial applications because of their high permittivity and piezoelectricity around room temperature. Although the microscopic mechanism of the relaxor behavior has not been fully elucidated yet, there are some fundamental developments in the experimental studies in the last decade, which are briefly reviewed in this ...
