Abstract

We report that an obvious difference in the "domain stabilization" effect between 1.0mol.%Mn doped (Ba1-xSr x)TiO3 and (Pb1-xSrx)TiO3 piezoelectrics with a similar c/a ratio and aging treatment, though typically "increased" stabilization effect occurs with the increase of c/a in each system. The three-time larger microscopic defect dipole field Ei in lead-system from P-E measurements suggests the more aligned defect dipoles through kinetically easier hopping of oxygen vacancy originated from local structure rather than the average structure like c/a may be a primary cause of the strong domain stabilization effect. This may help on the hardening functionality improvement of lead-free systems.
