|Title:||Nonmonotonic Temperature Dependence Of The Thermal Hall Angle Of A Yba2cu3o6.95 Single Crystal|
|Abstract:||We have performed high-resolution measurements of the magnetic field (0 T ≤ B ≤ 9 T) and temperature (10 K ≤ T < 140 K) dependence of the longitudinal and transverse Hall thermal conductivity of a twinned YBa2Cu3O6.95 single crystal. We have used and compared two recently published methods to extract the thermal Hall angle θ H(T, B). Our results indicate that cot(θH) varies quite accurately as T4 in the intermediate temperature range ∼ 0.3 < T/Tc. It shows a well defined minimum at Tm ≃ 20 K which resembles that observed in the c-axis microwave conductivity. The electronic part of the longitudinal and the transverse thermal conductivity show the scaling behavior for transport properties predicted for d-wave superconductors in the temperature range ∼ 18 K ≤ T ≤ 30 K.|
