Abstract
We have measured the isomagnetic temperature dependence of the anomalous Hall effect that arises from the asymmetric scattering of the conduction electrons by the localized moments in two alloys of Au containing ∼8.1 at.% Fe or Mn. The experiment is evidently a sensitive way to detect the magnetic rearrangement in a spin-glass. It shows clearly the spin-glass transition and features that are tentatively ascribed to the presence of magnetic clusters and "loose spins."Keywords
