Scaling behavior and giant field-enhancement of the thermal conductivity in the honeycomb antiferromagnet BaCo2(AsO4)2

Jiayi Hu, Ruidan Zhong, Peter Czajka +3

The layered honeycomb material BaCo${}_2$(AsO${}_4$)${}_2$ (BCAO) is of topical interest because its magnetic state is related to that of the Kitaev magnet $\hat{I}\pm$-RuCl${}_3$. Using thermal t…
