Thermoelectre properties were induced in polycryslatalline PbZrO[3]. The thermal depolarization method was applied to the charge evalation absorbed in the process of electret forming. Measurements were carried out near ...

The evidence of slaw discharge currents in PbZrO[3] near the phase change is given. Current measurements were carried out in the temperature range 180°C-280°C. The results prove the existence of three exponentially ...

The review of the most important theoretical considerations explaining the shape of I-V characteristics for ferroelectric materials is done. The assumptions and calculations proposed by Fridkin-Kreher and Krapivin-Chensky ...

This work is a theoretical introduction to the problem of the phenomenology of phase transition. A particular attention was paid to the characterization of ferroelectric transitions of the kind of order-disorder. The ...

A design of a new quartz thermostate is described. It controls: 1) The temperature of the sample from ambient temperature to 1270 K, 2) The pressure of the atmospheric air or other gases within the range from $133,3°10^{-6}$ ...
