Resumo: Lead niobate thin films have been prepared by laser ablation, at different substrate temperatures (Tdep) and with different oxygen pressures (pO2). For low deposition temperatures the films presented a rhombohedric-PbNb2O6 structural phase, with hysteresis cycles characteristic of a paraelectric. As Tdep increased the films started to develop an orthorhombic- PbNb2O6 structure that appeared at 400ºC and remained up to 600ºC. For low pO2, a mixture of this phase and a lead deficient phase was present in the films. Increasing the oxygen pressure the lead deficient phase was strongly reduced and the films presented only the ferroelectric orthorhombic- PbNb2O6 structural phase.
