dc.description.abstractA series of isovalently A-site substituted relaxor dielectric tetragonal tungsten bronzes of general formula Ba6-x-ySrxCayGaNb9O30 were investigated. The long-range (average) crystal structure as determined by conventional diffraction techniques varies monotonically according to Vegard’s law. The dielectric properties, however, do not display a similar, simple “average size” dependence and instead show a dependence on the statistical size variance, i.e. size mismatch, of the A-cation. The difficulties in Vogel-Fulcher analysis of relative permittivity and the complementary approach of using dielectric loss data fitted to Jonscher’s empirical Universal Dielectric Relaxation model is discussed.
