0.7Pb(Mg 1/3 Nb 2/3 )O 3 –0.3PbTiO 3 (PMN–PT 70/30) thin films, 400 and 600 nm thick, have been grown on Pt and LaNiO 3 (LNO) bottom electrodes by rf magnetron sputtering. For each thickness, local piezoelectric hysteresis loops evidence that the individual PMN-PT grains deposited on LNO always require much higher voltage than the ones grown on Pt for switching. The average piezoelectric activity of grains is shown to be the highest for LNO electrode. For each electrode, film thickness has no significantly effect on the average coercive voltage and piezoelectric activity measured on the loops. A simple charge model explains this result.
