Fig. 2: Temperature dependence of thermal Hall effect kXY/T.
From: Robustness of the thermal Hall effect close to half-quantization in α-RuCl3
Temperature-dependent kXY/T data in order of increasing in-plane magnetic field from 7.6 T (top left) to 13.2 T (bottom right). The independent results of temperature sweeps at a fixed field (coloured points) and field sweeps at a fixed temperature (black points) are plotted together to demonstrate the high degree of consistency. From 10.3 T onwards, a kink is visible at around 6.5 K (red arrows); beyond this field, the low-temperature magnitude of kXY/T is gradually enhanced towards the half-quantized value kHQ/T (dashed line). The grey-shaded areas emphasize the temperature range below 6.5 K. The error bars represent one standard deviation.
