Dielectric Properties of a Nanocomposite from RbNO₃ Incorporated into Pores of Al₂O₃ Matrix

Abstract

The present work reports the experimental results of studying linear and nonlinear dielectric properties of a ferroelectric nanocomposite from RbNO₃ embedded in pores of an Al₂O₃ matrix. The dielectric relaxation times were determined above and below the phase transition temperature of pure RbNO₃ (436 K). It was shown that for RbNO₃ incorporated into nanosized pores of the Al₂O₃ matrix, a decrease in the phase transition temperature and a change in relaxation times were observed.
