Abstract

The electric susceptibilities χ 1, χ 2, and χ 3 of BaTi1-xSnxO3 ceramics with 0.175≤ x≤ 0.30 are measured at 90≤ T≤ 350K and 37≤ f≤ 106Hz. Crossover from ferroelectric (x=0.175) to relaxor behavior (x=0.30) via coexistence of both (x=0.25) is indicated by increasing polydispersivity and suppression of χ 2 intensity. The relaxor properties are due to weak random fields acting on dipolar Ti4+ clusters in non-polar Sn4+ environment. Upon cooling frustrated interaction between the blocked polar nanoregions yields a cluster glass ground state for x=0.30 as verified by the dynamic criticality of χ 1, χ 3, and the scaled non-linear susceptibility a3. © 2014 AIP Publishing LLC.
