Abstract Starting from the free energy of a moving vortex, we obtain the extended power law form of longitudinal resistivity ρxx and the analytical form of Hall resistivity ρxy. Based on them, we obtain a scaling relation which agrees well with the experimental data of different kinds of high-temperature superconductors. Furthermore, the theoretical results well fit the scaling results.
