Abstract: 
manganese oxide La0.7Sr0.3MnO3 produced on (001) LaAlO3 substrate by means of sol-gel spin-coating method was used as the base electrode of LaSrMnO/Al2O3/Fe tunnel junctions. The I-V characteristic in the high bias region of this system was shown to be similar to that of the conventional tunnel junctions. Anomalous temperature dependence of tunneling resistance was observed to be a positive temperature coefficient of resistance. This phenomenon was attributed to the high voltage applied and was simply elucidated from the density states vs. energy diagram.
