Abstract
Recent theoretical investigations predict that the thermal filling of trap centers could lead to an intricate sequence of phase transitions with unstable boundary state between the phases. This fact has motivated the experimental study of ferroelectric phase transitions in TlInS/sub 2/ composites where the cationic impurities can form the capture levels (traps) at the bottom of the conduction band. In this paper the results of experimental investigation of dielectric, polarization and pyroelectric properties of TlInS/sub 2/ composites are presented. It was shown that TlInS/sub 2/ composites display all peculiarities that are typical for relaxor ferroelectrics.
