Insight into the dynamics of low temperature dielectric relaxation of ordinary perovskite ferroelectrics

New Journal of Physics, 2017
The temperature dependence of the dielectric response of ordinary ferroelectric materials exhibits a frequency-independent anomalous peak as a manifestation of the ferroelectric to paraelectric phase transition.

Magnetic and ferroelectric phase coexistence in multiferroic PFW-PT ceramics [PDF]

Processing and Application of Ceramics, 2012
The multiferroic (1-x)PbFe2/3W1/3O3–xPbTiO3 solid solutions with various compositions x = 0, 0.10, 0.20 and 0.30 were investigated. The features of the relaxor-to-ferroelectric transition with increasing x were discussed based in connection with ...
