N2 - Donor-doped PbZr 0.52Ti 0.48O 3 (PZT) films were utilized to study the effect of dopants on the mobility of ferroelectric domain walls. For chemical solution deposited PZT films 2 μm in thickness, doped with 1%-4% Nb or La, the low field dielectric permittivity remained between 1100 and 1300. With increasing Nb concentration, both the reversible and irreversible Rayleigh constants increased from ε init and α' of 1150 and 39 cm/kV, respectively, for undoped PZT films to 1360 and 43 cm/kV for films doped with 2 mol% Nb. La doping increased the irreversible Rayleigh constant but did not strongly affect the reversible Rayleigh parameter. These observations are consistent with softening of the dielectric and electromechanical response with donor doping.
