Analysis of electrical properties using complex impedance spectroscopy in solid solutions (PbTiO3)0.97-(LaFeO3)0.03 prepared by sol-gel technique

The AC complex impedance spectroscopy technique was utilized to extract electrical parameters in (PbTiO 3 ) 0.97 -(LaFeO 3 ) 0.03 ceramic in wide ranges of frequencies and temperatures. The sample was prepared by sol-gel process and the single phase was confirmed using x-ray diffraction. The compoun...

Description
Summary:The AC complex impedance spectroscopy technique was utilized to extract electrical parameters in (PbTiO 3 ) 0.97 -(LaFeO 3 ) 0.03 ceramic in wide ranges of frequencies and temperatures. The sample was prepared by sol-gel process and the single phase was confirmed using x-ray diffraction. The compound exhibits high dielectric constant ( ε r max ~ 6050) for 1 kHz and low dielectric losses ( tanδ
