Effect of Sn doping on the properties of yttrium modified lead zirconate titanate stannate system

The effects of stannate doping on the phase transition, P-E electrical hysteresis and shape memory behaviors of yttrium modified lead zirconate titanate stannate (with Ti=0.085) were examined. The increasing Sn/Zr ratios were investigated experimentally for their effect on obtaining the antiferroelectric phase at room temperature. It is observed that although the strain increases with increasing Sn/Zr ratio, all the samples (except x=0.4 and 0.5) are ferroelectric at room temperature. The sample with x=0.4 that was reported [Ref.2] to be antiferroelectric at 40°C, shows paraelectric or compensated AFE behavior at room temperature.
