| Abstract: | 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 (T c) as low as 71 K. The Hall conductivity in the mixed state follows theC 1/H+C 2 H field dependence. The absolute value of the coefficientC 1 increases faster than (1–T/T c) with decreasing temperature.C 2 increases rapidly asT falls belowT c. The temperature dependence of the ratioC 1/C 2 scales approximately asT/T c for different levels of zinc doping. |
