Thickness dependence of transverse SNMR in W/CoFeB and Pt/CoFeB structures. a, b Laser-position-dependent thermoelectric signal V 2θ for W/CoFeB structure (a) and Pt/CoFeB structure (b) with different HM thicknesses ranging from 1 to 5 nm. Black arrow represents position of edge illumination. c, d HM thickness dependence of the V 2θ for edge illumination for W/CoFeB structure (c) and Pt/CoFeB structure (d). The white circles represent experimental data and solid lines represent best fitted curves, while purple band indicates error ranges of extracted values, which originated from uncertainties of S HM, G, and θ SH. Error bars represent the range of the measured values, resulting from laser-position uncertainty
