| Abstract: | In this study, the AC conductivity of insulating Gd1/3Sr2/3FeO3 was analyzed within the framework of the quantum-mechanical tunneling mechanism (QMT) and the hopping of barrier mechanism (HOB). Experimental data were taken from 20 Hz to 1 MHz and from 80 to 300 K. Observation revealed that the small polaron QMT model is the more suitable mechanism for modeling the AC conductivity of Gd1/3Sr2/3FeO3 at low temperatures. |
