Planar Thermal Hall Effects in Kitaev Spin Liquid Candidate Na2Co2TeO6

Hikaru Takeda, Jiancong Mai, Masatoshi Akazawa +7

We investigate both the longitudinal thermal conductivity (${\kappa }_{xx}$) and the planar thermal Hall conductivity (${\kappa }_{xy}$) in the Kitaev spin liquid candidate of Co-based honeycomb a…
