Fig. 3: USMR characterization.
a The schematic graph of measurement setup, b The angular dependent longitudinal first harmonic resistance \({R}_{{{\rm{xx}}}}^{1{{\rm{\omega }}}}\), c The SMR ratio for samples with the different thicknesses of Pt, d The Pt-thickness dependent SMR ratio, e The angular dependent second harmonic resistance \({R}_{{{\rm{xx}}}}^{2{{\rm{\omega }}}}\), f \({R}_{{xx}}^{2{{\rm{\omega }}}}\) as a function of magnetic field Hy at various I0 with \({t}_{{{\rm{Pt}}}}\) = 1.5 nm, g The USMR ratio \(({R}_{{{\rm{USMR}}}}/J)/{R}_{{{\rm{xx}}}}^{1{{\rm{\omega }}}}\) as a function of \({t}_{{{\rm{Pt}}}}\), h Comparison of the room-temperature USMR in different systems. Error bars represent the uncertainty of test results from multiple devices.
