Magnetization switching caused by current-generated spin-orbit torques in heavy metal/ferromagnetic metal/heavy metal heterostructures has become a significant issue due to its excellent performance in low-power and high-density storage applications. In our work, based on Pt/Co/W and Pt/Co/W0.82Pt0.18 structures with perpendicular magnetic anisotropy (PMA), the effective spin Hall angles (theta SHeff
