Abstract
Temperature dependences of the linear permittivity ε' and the third harmonic amplitude γ3ω of composites prepared by introducing ferroelectrics SC(NH2)2 into matrices of porous aluminum oxide Al2O3 with pore sizes 60 and 100 nm are determined. It is found that temperature Tc of the ferroelectric phase transition and the temperature Ti of the phase transition from incommensurable phase to the paraphrase increase significantly. The transition shifts increase as pore diameters decrease.
