Dynamic response of TGS ferroelectric samples in paraelectric phase

Triglycine sulfate (TGS) is well known and one of the most extensively studied model ferroelectric materials. Previous experiments proved some kind of order in the paraelectric phase which resulted in an electric response to the fast temperature pulses above the critical temperature T-c. This paper presents the novell method for experiments and studies of the electric properties of TGS, in relation to domain switching under precisely controlled temperature pulses. We designed a new virtual measurement device based on LAB VIEW and redesigned the thermostatic sample holder with Peltier cells as heating/cooling elements. (C) 2015 Elsevier B.V. All rights reserved.
