Abstract

The temperature (T) dependence of the quasi-equilibrium conductivity (T) of iron-doped, oxygen-reduced, and undoped BaTiO3 single crystals and relaxor (Pb(Zn1 /3Nb2/3)O3)0.92 (PbTiO3)0.08 (PZNT-PT) crystals is measured. We have found that all the -T's exhibit the peaking at Curie temperature as far as the conductance in the paraelectric phase is sufficiently low. The value of the peaks of BaTiO3 single crystals is approx. 1 n- 1cm- 1 and is independent of impurities, whereas of the paraelectric phase depends on impurities. We speculate that the conductance peaking at phase transitions is a general property of ferroelectrics.
