Spin rectification effects in ferromagnetic metal microstrips induced by anisotropic magnetoresistance, planar Hall effect, and anomalous Hall effect

Spin rectification effect (SRE) is an important electrical detection tool employed to probe magnetic dynamics and spin-orbit torques, and it is also closely related to spin pumping measurements. The SRE has multiple physical origins, and the entanglement among them makes it difficult to derive quantitative information. Herein, we present a systematic study of the SRE in ${\mathrm{Co}}₄₀{\mathrm{Fe}}₄₀{\mathrm{B}}₂₀$ and Ni microstrips with out-of-plane-dominant microwave magnetic field excitation. The SREs from different physical mechanisms can be quantitatively decomposed via a symmetry consideration. The validity of the method is further supported by angular-dependent analyses. We observe both the anisotropic magnetoresistance induced SRE from the longitudinal induction current, and the planar Hall effect as well as the anomalous Hall effect induced SREs from the transverse induction current. Our work provides a comprehensive understanding of the SREs in ferromagnetic metal microstrips, and it is beneficial for quantitative analyses in microwave-related studies in spintronics.
