Abstract
shows a large anomalous Hall effect that is dominated by a skew contribution arising from the asymmetric scattering of the itinerant electrons. We have measured this effect in alloys ranging from the dilute limit up to concentrations for which overlap is the dominant intermoment coupling (Au + 211 at. ppm Fe to Au + 8.64-at.% Fe). We show that the qualitative behavior of the skew component does not change over this wide concentration range, and does not correlate with the magnetization. The results suggest a cause more complicated than one involving isolated scattering by ions coupled through the Ruderman-Kittel-Kasuya-Yosida interaction.
