This paper reports on the magnetotransport behavior of Fe-Al 2 O 3 granular thin films when the injected dc current is varied. The electric resistance as a function of temperature, magnetoresistance, and the current vs applied bias potential measurements were used to characterize the samples. It was found that the transport mechanism which best describes the electronic properties of these samples is variable range hopping. Non-Ohmic behavior was observed and is claimed as responsible for thedoi:10.1063/1.1479481 fatcat:5z2uwsa3a5d47pzrin5mwmyili
