Abstract

Dielectric properties and IR spectra have been studied for ferroelectric nanocomposites: porous glass–NaNO₂ and porous Al₂O₃–NaNO₂. The effect of depolarization field on dielectric properties and phase transition has been analyzed. The role of the “matrix-embedded ferroelectric” interface is discussed.
