Robustness of the thermal Hall effect close to half-quantization in a field-induced spin liquid state

J. A. N. Bruin, R. R. Claus, Y. Matsumoto +3

Thermal signatures of fractionalized excitations are a fingerprint of quantum spin liquids (QSLs). In the $J_{eff}=1/2$ honeycomb magnet $\alpha$-RuCl${}_3$, a QSL state emerges upon appl…
