Recently, we demonstrated the detection of spin-orbit-torque magnetization switching by using the rectification signal under microwave irradiation (low frequency spin torque ferromagnetic resonance: LFST-FMR). This method does not need any complicated nanostructures such as magnetic tunnel junctions. Therefore, LFST-FMR is expected to realize agile research on various materials combination of nonmagnet (NM)/ferromagnet (FM) layers. In this study, we investigated the spin rectification effect of several kinds of NM/FM bilayers. In this presentation, we discuss the origin of FM and NM dependent characteristics of spin rectification signal in detail.
