Observation of magnon Hall-like effect for sample-edge scattering in unsaturated YIG

We report the observation of a magnon Hall‐like effect for the scattering of magnons at the sample edge in Y3Fe5O12 crystals. The experiments are performed under an out‐of‐plane magnetic field at room temperature using an infrared thermometry. When the magnons are incident into the sample edge in th...

Summary:We report the observation of a magnon Hall‐like effect for the scattering of magnons at the sample edge in Y3Fe5O12 crystals. The experiments are performed under an out‐of‐plane magnetic field at room temperature using an infrared thermometry. When the magnons are incident into the sample edge in the unsaturated magnetic structure, appreciable transverse thermal gradient is detected. This thermal gradient could be attributed to magnon Hall effect for sample‐edge scattering. We unexpectedly find that this effect is largely enhanced in the unsaturated regime, compared with the saturated regime where theoretical mechanism of magnon Hall effect due to the Berry curvature has been proposed previously.
