dc.descriptionWe find universal scaling relations of the pinning effect on the Hall resistivity $ρ_{xy}$ and Hall angle $θ_{H}$. Considering the extended power law form of $ρ_{xx}$ and the microscopic analysis of $σ_{xy}$, we obtain unified $ρ_{xy}$ equations for superconductors with and without double sign reversal. These equations reasonably explain the striking universality in doping dependence found by Nagoaka et al., which contradicts the prediction of the time dependent Ginzburg-Landau equation based on s-wave coupling theory [PRL {\bf{80}},3594 (1998)]. A full comparison of experiment with prediction from theoretical models is proposed.
