Abstract

Lead magnesium niobate thin films have been grown on {100} MgO substrates using pulsed laser deposition (PLD). Several series of films were made using targets of varying perovskite and PbO content. The conditions necessary to produce almost 100% perovskite Pb(Mg1/3Nb2/3)O3 (PMN) films were most sensitive to the growth temperature rather than the starting target crystallography. The electrical properties were determined by fabricating planar thin film capacitor structures and monitoring capacitance and dielectric loss as a function of temperature. Our best capacitors yielded a loss of 0.1 at 1 kHz over a wide temperature range.
