We study the flux-flow Hall effect and thermomagnetic transport near the upper critical field ${\mathit{H}}_{\mathit{c}2}$ in extreme type-II superconductors starting from a suitable generalization of the time-dependent Ginzburg-Landau equations. We explicitly incorporate the effects of backflow into the calculations of the local electric field and current, which leads to a …
