Superlattice (SL) thin films with different periods and composition ratios of Pb(Sc1∕2Nb1∕2)O3 and PbTiO3 (PT), inside and outside the morphotropic phase boundary, are synthesized by a pulsed laser deposition method. High order SL reflections are observed by x-ray diffraction, from which the SL period and correlation length are determined. The coherency of the SL structure is found to extend over the whole film in the thinner films. A maximum dielectric constant of 1800 with a dielectric loss of 0.05 is obtained in the frequency range of 1–104Hz for a SL with average composition of 25% of PT.
