| Abstract: | ABSTRACTThe present work aims at investigating linear and nonlinear dielectric properties of nanocomposites based on diisopropylammonium bromide (C6H16NBr, DIPAB) embedded into Al2O3 films having honeycomb structure with pores of 100?nm in diameter, and into opal matrices with three-dimensional structure containing pores of 100 and 60?nm. The obtained results indicated the shift of Curie point toward lower temperatures for DIPAB in porous aluminum oxide and the appearance of two phase transitions, detected upon heating and cooling for DIPAB in opal matrices. In addition, a ferroelectric phase was found to form between these two phase transitions without significant change of Curie temperature. |
