Extended Data Fig. 5: SMR for a geometry with the wires along y (μ along x).
From: Tunable long-distance spin transport in a crystalline antiferromagnetic iron oxide
The red and black circles show data for H along x (perpendicular to the wire) and along y (parallel to the wire), respectively. The jump in resistance around 8–10 T for H parallel to the wire (black) corresponds to the DMI-induced Hc (Methods section ‘Modelling of the Néel order and magnetization orientations’). The jump in resistance at 6 T for H perpendicular to the wire (red) correspond to the more classical Hc. The solid lines correspond to a combined regression fit of the H-along-x and H-along-y data of the spin-mixing conductances from equations (4)–(6), yielding \({g}_{{\boldsymbol{n}}}^{(\uparrow \downarrow )}\) = 31.77 nm−2 and \({g}_{{\rm{r}}{\boldsymbol{m}}}^{(\uparrow \downarrow )}\) = 136.52 nm−2. The two field directions are fitted together with \({g}_{{\rm{i}}{\boldsymbol{m}}}^{(\uparrow \downarrow )}=0\), K/J = 0.025 and D/J = 0.011, using λ = 2 nm, θSH = 0.1 and ρ0 = 40 μΩ cm for the normal metal wires.
