We have studied the polarity of magnetoresistance (MR) in three types of magnetic junctions. While the NiFe/single layer graphene (SLG)/Co and NiFe/Al<sub>2</sub>O<sub>3</sub>/Co junctions showed spin valve signals with positive MR, the NiFe/Al<sub>2</sub>O<sub>3</sub>/SLG/Co junction revealed negative MR values.
