We have investigated scaling of anomalous Hall resistivity with longitudinal resistivity (ρxx) in pyrochlore type Nd2(Mo1-xNbx)2O7 with spin chirality. Scattering rate of the conduction electron on the Mo sublattice can be varied with x from band transport to polaron hopping, while keeping the two-in-two-out structure of the Nd moments intact. The anomalous part of the Hall resistivity arising from the Mo spin chirality (ρHχ) shows a clear scaling behavior with ρxx (ρHχ ρxx0.39), in accord with a recent theoretical result based on the Berry phase mechanism in the hopping conduction regime.
