AC low frequency conductivity in PZT PFS ferroelectric ceramics

Andrzej Osak

Abstrakt

Low frequency AC conductivity has been studied in ferroelectric ceramics PZT + PFS (Pb[(Fe1/3Sb /3)xTiyZrz]O3 with x = 0.1 and y = 0.43, 0.44, 0.47) using Fourier transformation of charging and discharging currents. The results are interpreted in terms of fractal structure of the randomly generated clusters formed by sequentially correlated hopping paths of charge carriers.
