Flux-flow Hall-effect problem: Comparison of the theory of Nozières and Vinen with results in 2H-NbSe2

The old problem of the flux-flow Hall effect is investigated in single-crystal 2H-${\mathrm{NbSe}}_2$. We find that the Hall signal, particularly the constancy of the Hall angle with field, is correctly described by the theory of Nozières and Vinen (NV). The dependences of ${\mathrm{\theta }}_{\mathit{H}}$ on the field, current density, and temperature are compared in some detail with the version of NV’s model that assumes a finite pinning force.
