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