Fig. 2: Spin transport in YFeO₃ at 200 K.

a R_el as a function of field applied along easy-axis for device where wires are parallel to easy-axis. Initially n is parallel to the field and perpendicular to μ_s, which shows zero spin transport signal. On increasing the field n rotates smoothly yielding a gradual increase in R_el, followed by a maximum and the signal vanishes above H_cr where n becomes perpendicular to the field. b R_el as a function of field applied along the easy-axis for the device where the wires are perpendicular to easy-axis. In spite of n parallel to μ_s at zero magnetic field, no zero-field spin transport is observed. R_el increases with field initially and reaches a maximum at μ₀H = 3 T followed by a decrease and the signal diminishes above critical field. The error bars are the standard error of the mean. In both curves, the signal is plotted after subtracting the offset at zero field. The solid blue lines based on the theoretical model are described in the text. In both of the geometries, the centre-to-centre distance between the wires is about 525 nm.
