Abstract

We have observed the dielectric response of SBN−75+0.01 at.% Cr single crystal in the area of the diffuse phase transition. The effect of illumination and exposure (ageing) on the character of ε'(E=) has been displayed. We show that the memory effects typical of the relaxors disappear almost completely under illumination of SBN−75+0.01 at.% Cr single crystal.
keywords Strontium−barium niobate, reversible permittivity, photodielectric response, dielectric memory effect.
