Lead zirconate titanate (PZT) thin films were deposited on stainless steel (SS) substrates by a sol-gel spin-on technique, and crystallized by a low-temperature annealing process. A lead titanate thin coating was deposited between the PZT film and SS substrate in order to decrease the annealing temperature. X-ray diffraction revealed that amorphous PZT thin layers crystallized into a perovskite phase on annealed at 550 degreesC for 0.5 h. No second phase formation, due to chemical reactions with the substrate, was observed. For films with a thickness of 1.68 mum, the dielectric constant, tan delta, remnant polarization and coercive field were determined to be 280, 0.07, 35 muC/cm(2), and 99 kV/cm, respectively. The transverse piezoelectric constant d(31) was measured using a wafer flexural technique. (C) 2002 American Institute of Physics.
