摘要：

We propose an empirical formula for the anomalous Hall effect in heavy electron materials based on a phenomenological two-fluid description of the f-electron states. This formula incorporates two previous theories, proposed by Fert and Levy in 1987 and Kontani et al. in the early 1990s, and takes into account both incoherent and coherent skew scatterings from local and itinerant f electrons. We perform experimental analysis in several heavy electron compounds and show that the formula provides a consistent description of the evolution of the Hall coefficient in the whole temperature range down to only a few Kelvin.
