X-ray diffraction pattern of PFN thin films over a wide range of Bragg’s angle . The inset is a zoom on the (002). Those peaks marked with correspond to extra LSCO/MgO peaks but their intensities are less than 0.3%–0.5%.
Complex dielectric constant as a function of temperature, i.e., dielectric constant vs for 5–100 kHz in the arrow direction. (lower inset) vs for 5–100 kHz in the arrow direction. (upper inset) Dielectric anomaly between 200 to 600 Hz.
vs relationship of PFN films in the vicinity of . (Inset) Dielectric constant at at lower temperatures. The blue line corresponds to the extrapolated dielectric constant from the paramagnetic range.
hysteresis loop for PFN film at room temperature. (upper inset) ZFC and FC magnetizations of PFN films as a function of temperature under an applied magnetic field of 100 Oe. (lower inset) Vogel–Fulcher fitting of the PFN thin films.
