Resum
A study of the substitution influence of Nb5+ and Fe3+ impurities on piezoelectric behaviour has been carried out. Different substitution concentrations as well as undoped materials have been performed for ceramics Pb(Zr1 - xTix)O3 with x = 47 and 40. The different impurity concentrations, and their type, produce variations in the domain wall mobility related to the extrinsic coefficient. This dependence between extrinsic behaviour and impurity concentration is studied for different material str...
