Abstract
We present a way to extract the quasiparticle thermal conductivity kappa(e) and mean free path in YBa2Cu3Ox using the thermal Hall effect and the fiel d dependence of kappa(e). The results compare well with heat capacity exper iments. Moreover, we find a simple relation between the thermal Hall angle theta(Q) and the H dependence of kappa(e), as well as numerical equality be tween theta(Q) and the electrical Hall angle. The results also reveal an an omalously anisotropic scattering process in the normal state.
