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 $133,3°10^{-6}$ ...

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 ...
