【 摘 要 】

In this letter, we study the contemporary technologies for making ferroelectric films and the possibility of using the oscillator model of PZT-22 to analyze its ferroelectric properties. The material showed permittivity dispersion at 65 KHz and 88.5 KHz. We obtained relative attenuation γ, relaxation time τ, and max of the material as 0.0008319, 0.5 s, and 603.438, respectively.
