a Measurement circuit, b ST-FMR resonance spectrum in Mn3Sn/Ni-Fe bilayer. c, d Schematic image of an out-of-plane component of spin accumulation at Mn3Sn/Ni-Fe interface. e, f Resonance field shift by dc current (e ΔHr=Hr (φ=−45°, θ=45°)-Hr(φ=−45°, θ =135°), f ΔHr=Hr (φ=135°, θ =45°)-Hr(φ=135°, θ =135°)) Error bars represent the standard deviation of five replicate measurements. Input radio frequency and power are 13 GHz and 7 mW.
