Abstract

The intrinsic, reversible, and irreversible extrinsic dielectric responses of 0.27Pb(In1/2Nb1/2)O3-0.46Pb(Mg1/3Nb2/3)O3-0.27PbTiO3 relaxor single crystals with and without Mn doping have been extracted by using Rayleigh analysis from 0.1 Hz to 1000 Hz, and the influence of acceptor ions has been quantitatively evaluated. The results show that the lattice deformation under an ac electric field is slightly inhibited by Mn2+/Mn3+, while both reversible and irreversible domain wall motions are greatly suppressed to below 20% of the non-Mn doped values. As a result, the mechanical quality factor, which is closely related to domain wall motions, is significantly enhanced. Meanwhile, the large piezoelectricity, which is dominated by intrinsic contribution, is maintained.
