Abstract: Lead magnesium niobate-lead titanate (0.67Pb(Mg1/3Nb 2/3)O3-0.33PbTiO3, PMN-PT) thin films have been successfully deposited on Pt/Ti/SiO2/Si substrates by RF magnetron sputtering. Annealing at 550°C led to a well established perovskite structure. The annealed films exhibited well-defined hysteresis loops, with a respective remanent polarization (2Pr) of 27.4μC/cm2 and coercive field (2Ec) of 58.6kV/cm at an applied electric field of 250KV/cm at room temperature. A dielectric constant of 947 and a dielectric loss of 3.8% were measured for the PMN-PT thin film at 100kHz. The annealed films were found to be little fatigue even after 1010 number of switching cycles. The ferroelectric properties of these PMN-PT thin films, which are compared favourably with those of PMN-PT thin films via other deposition routes, are accounted for by their structural features. © 2004 Elsevier Ltd. and Techna Group S.r.l.
