The interfacial Dzyaloshinskii-Moriya interaction (iDMI) in asymmetric magnetic multilayer films has displayed increasingly important roles in the modification of domain walls, stabilization of Skyrmions, and realization of new topological spin textures such as magnetic radial vortices. Unlike magnetization and magnetic anisotropy which can be readily measured, iDMI is difficult to measure. In this work, we measured the iDMI in Pt/Co/Ir and Pt/Co/Ru multilayer films by exploring the spin-orbit torque induced effective field under an in-plane bias magnetic field. Skyrmions have been reported to exist in Pt/Co/Ir multilayers. We found that Pt/Co/Ru multilayers have a similar magnitude of the iDMI for Pt/Co/Ir multilayers, suggesting that Pt/Co/Ru is a good candidate to host Skyrmions.
