Abstract

Temperature dependences of permittivity ε′ and third harmonic amplitude γ of nanocomposites obtained by embedding ferroelectric SC(NH2)2 in porous alumina films with pore sizes of 60 and 100 nm are studied. A substantial increase in the temperatures of ferroelectric phase transition Tc1 and Tc2 and that of phase transition Ti from incommensurate phase to paraphase are also observed. The temperatures of all phase transitions are found to rise as pore diameters shrink.
