We measured the planar Hall effect (PHE) of magnetite films between 150 and . The PHE was measured both with a constant magnetic field rotating in the plane of the sample and in a remanent state after applying a field in specific directions. The PHE amplitude decreases with temperature; however, it changes little between 300 and . The remanent PHE signal is as high as , larger than previously observed in manganite films. We also measured the PHE in the remanent state and found that its magnitude and stability make it a viable candidate for magnetic random access memory applications.
