Fig. 6. Frequency dependence plots of the real part of electrical modulus, M′ in the temperature range from −100 °C to 100 °C with steps of 20 °C, (a) the pure LaCrO3, inset shows its log–log plots of the real part of modulus with frequency (b) temperature vs. M′ plot for LCO at 102, 103, 105 and 107 Hz. (c) M′ vs. applied frequency for Ir doped LCO sample (inset figure shows temperature vs. M′ plot at 102, 103, 105 and 107 Hz) and (d) semi-log of the real part of modulus with frequency of the LaCr0.90Ir0.10O3.
