ABSTRACT
Current-perpendicular-to-plane transport properties of sputtered polycrystalline Fe3O4/α-Fe2O3 heterostructures were investigated. A rectifying behavior was observed. The voltage shift increases linearly with temperature and turns from negative to positive at 230 K. The current-dependent magnetoresistance (MR) changes from negative to positive in the temperature range of 230–260 K. The largest negative MR is -32% at 230 K, and the positive MR at 305 K reaches 80% at 1.0 mA. The characteristic MR is thought to be caused by the rectifying effect and band structure at the Fe3O4/α-Fe2O3 interface.
