摘要：

The spin Hall torque induced by DC current was studied experimentally. A Pt/Co/Pt structure with perpendicular magnetic anisotropy was grown, and magnetization reversal due to the spin Hall effect was observed. An extra magnetic field perpendicular to the sample was applied in addition to a constant bias field. It was found that the switching current shifted in proportion to the additional perpendicular field. The spin Hall angle was estimated from this relation, and the small perpendicular magnetic field can be measured accurately based on this effect.
