The effect of zinc doping on the mixed-state Hall effect in detwinned single crystals of YBa2Cu3O7-δ has been studied. We observe a sign reveral of the Hall effect in crystals with a superconducting transition temperature (Tc) as low as 71 K. The Hall conductivity in the mixed state follows the C1/H+C2H field dependence. The absolute value of the coefficient C1 increases faster than (1-T/Tc) with decreasing temperature. C2 increases rapidly as T falls below Tc. The temperature dependence of the ratio C1/C2 scales approximately as T/Tc for different levels of zinc doping. © 1996 Plenum Publishing Corporation.
