Abstract

The electric susceptibilities χ _1, χ ₂, and χ ₃ of BaTi_1-xSn_xO₃ 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.
