Abstract
Here we report the relaxor behavior of pure and cerium doped Czochralski grown lead free relaxor ferroelectric single crystals CaxBa1-xNb2O6 (CBN-x) (0.18 ≤ x ≤ 0.35) using temperature dependent elastic behavior. We observed that the dynamic relaxor behavior strongly varies with the variation of Ca content as well as with doping. Evidence is found for a more pronounced relaxor behavior with increasing Ca content and doping. Characteristic temperature T* (temperature at which static behavior of the polar nanoregions begins to appear) found to be unaffected with Ca content variation as well as doping.
