Fig. 2: Nonlocal magnon transport measurement.
From: A puzzling insensitivity of magnon spin diffusion to the presence of 180-degree domain walls
a Schematic drawing of the experimental setup for nonlocal measurements. b False-color scanning electron microscope image of the device, in which green indicates the Pt wires and yellow corresponds to the contact leads. c First harmonic R1ω and second-harmonic R2ω nonlocal signals as functions of the magnetic-field angle ϕ for a field magnitude of 75 mT and for Pt wires oriented along the [010] axis with a 1 µm separation.
