Extended Data Fig. 3: RIXS spectra at different sample locations.
From: Observing differential spin currents by resonant inelastic X-ray scattering
a, Sketch of the device, in which the color bar indicates temperature differences, similar to Fig. 2a in the main text. b, Magnon accumulation/depletion as a function of position x calculated for a constant gradient in a symmetric sample. The accumulation/depletion decays on the scale of the magnon relaxation length λ = 2 μm in red and 10 μm in black. c (e), RIXS spectra for q0.2 measured at the hot point (cold point) for two temperature gradients ΔT2 (dark blue) and ΔT4 (light blue). d (f), The RIXS intensity difference between spectra for ΔT2 and ΔT4 and their Gaussian fit (solid line).
