Low frequency AC conductivity has been studied in ferroelectric ceramics PZT + PFS (Pb[(Fe_1/3Sb_2/3)_xTi_yZr_z]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.

W artykule przedstawiono przewodnictwo zmiennoprądowe ceramiki ferroelektrycznej PZT + PFS (Pb[(Fe_1/3Sb_2/3)_xTi_yZr_z]O₃, gdzie x = 0.1 i y = 0,43, 0,44, 0,47) w zakresie ultra niskich częstotliwości obliczone na podstawie analizy Fouriera prądów polaryzacji i depolaryzacji dielektrycznej. Wyniki zostały zinterpretowane na podstawie fraktalnej struktury klasterów generowanych przez stochastyczny sekwencyjny hopping nośników ładunku.
