摘要：

The magnetic field and the temperature dependence of the mixed-state Hall effect have been measured on single crystals in the system Y1-xPrxBa2Cu3O7-delta (0.0 less-than-or-equal-to x less-than-or-equal-to 0.3) with the magnetic field perpendicular to the ab plane and the current flowing in the ab plane. A sign change of the Hall resistivity is observed at low Pr concentrations, with the negative Hall resistivity disappearing between the concentrations of x=0.1 and x=0.2. The field dependence of the Hall resistivity for various Pr concentrations can be qualitatively explained by incorporating a finite pinning force F(p) in the Nozieres and Vinen (NV) model.
