Angular dependency of the non-local voltages for Platinum wires along x at different applied magnetic field (below, at and above the spin-flop field Hc). a, The spin-bias signal Rel presents a 2α angular dependency as expected for a spin signal. b, The spin-Seebeck signal Rth presents a α angular dependency as expected for a thermally injected signal. The two signal show maxima, which are shifted by 90 deg. show that the electrical signal Rel corresponds to magnons injected along the Néel order while the the thermal signal Rth corresponds to magnons injected in the field induced magnetization.
