title = "Influence of Mn doping on domain wall motion in Pb(Zr0.52Ti 0.48)O3 films",
abstract = "Mn-doped PbZr0.52Ti0.48O3 (PZT) films were utilized to study the effect of acceptor dopant concentration on the mobility of ferroelectric domain walls. For chemical solution deposited PZT films between ∼0.5-2 μm in thickness doped with 1-2mol.% Mn, the low field relative permittivity remained between 900 and 1000. With increasing Mn concentration, a threshold field developed in the ac field dependence of the relative permittivity. Furthermore, both the reversible and irreversible Rayleigh constants decreased. These observations are consistent with the possibility that Mn′Ti - V{\"O} (or Mn″Ti - V {\"O} ) defect dipoles act as strong pinning centers.",
