Dispersion of Dielectric Permittivity in Thin Ferroelectric Lead Titanate Films
Lead titanate thin films were obtained by plasma-enhanced magnetron sputtering. Synthesized films demonstrate high temperature stability, relatively narrow maximum at temperature of phase transition for ε (T ) dependence, great dielectric constant value near the Curie point, saturated hysteresis loops, and relaxation character for dispersion of dielectric permittivity similar to bulk samples.
