“…The less frequency dependence at higher frequencies (⩾ 100 kHz) reflects clearly the lag of the hopping time and/or the alteration of the polarization behind the frequency of the applied electric field. [63][64][65][66][67] AC-conductivity.-Figure 10 depicts the variation in the real part of complex conductivity, σ′, as a function of frequency in the range of 0.1 Hz to 20 MHz at two selected temperatures namely, 303 and 423 K. The two selected temperatures were chosen just as representative examples. Although the base (LGFO) shows a perfect insulator compounds its σ′ decreases gradually or even linearly with frequency and its conductivity has a values in the order of sub-PicoSiemens (≈10 −13 ) per cm at lower limit of the frequency window (0.1 Hz), it behaves like many other conductive glasses, ionconducting glass-forming liquids and conductive polymers for the MCFO doped compositions.…”

“…The lower influence of composition, frequency, and temperature on the permittivity at higher frequencies is now a prominent feature in condensed matter physics. It is attributed to the lag of alteration of any dynamic fluctuation behind this higher frequency of the applied electric field [34][35][36][37]. However, ε′ increases slightly with decreasing frequency in the case of the two nanocomposites.…”
