We studied angle-dependent magnetoresistance in Pt/Fe3O4 bilayers at room temperature. Based on field-dependent and angle-dependent measurements, we show that spin Hall magnetoresistance (SMR) exists in the Pt/Fe3O4 system at room temperature, although the Fe3O4 layer is not a good insulator. The SMR contribution in Pt/Fe3O4 can be clearly identified for thin enough Fe3O4 films. Moreover, the SMR in Pt/Fe3O4 does not rely on the current direction, which is different from the anisotropic magnetoresistance in single-crystalline Fe3O4 films.
