Abstract
It is shown that the dielectric response ofBa0.77Sr0.23TiO3 nanoparticles at temperatures below 200 K has a frequency and temperature dependence inagreement with the Debye theory with a single relaxation time, which exhibits theArrhenius law. By contrast, at temperatures above 210 K the dielectric response exhibits abroad range of relaxation times characteristic of relaxor-ferroelectrics. We suggest that thesingle relaxation time at low temperature originates from a frustration effect, in analogywith frustrated antiferromagnetism.
