We fabricate Fe/Fe oxide granular film by DC sputtering and study the magnetic and transport properties in the insulator region. X-ray photoelectron spectroscopy and transmission electron microscopy confirm the coexistence of iron and Fe2O3. Accompanied with the nonlinear I-V curve and magnetic measurement, we investigate mechanism of sizable magnetoresistance in detail and found the spin in the interface has crucial contribution to the spin tunneling process.
