We have grown lead iron niobate thin films with composition Pb(Fe1/2Nb1/2)O3(PFN) on (0 0 1) SrTiO3 substrates by pulsed laser deposition. The influence ofthe deposition conditions on the phase purity was studied. Due to similarthermodynamic stability spaces, a pyrochlore phase often coexists with the PFNperovskite phase. By optimizing the kinetic parameters, we succeeded inidentifying a deposition window which resulted in epitaxial perovskite-phasePFN thin films with no identifiable trace of impurity phases appearing in theX-ray diffractograms. PFN films having thicknesses between 20 and 200 nm weresmooth and epitaxially oriented with the substrate and as demonstrated by RHEEDstreaks which were aligned with the substrate axes. X-ray diffraction showedthat the films were completely c-axis oriented and of excellent crystallinequality with low mosaicity (X-ray rocking curve FWHM<0.09). The surfaceroughness of thin films was also investigated by atomic force microscopy. Theroot-mean-square roughness varies between 0.9 nm for 50-nm-thick films to 16 nmfor 100-nm-thick films. We also observe a correlation between grain size,surface roughness and film thickness.
