Abstract
The transverse magnetoresistance in a monocrystalline Au+105 at ppm Fe alloy has been measured at 1.7K with the applied magnetic field along the (110), (111) or (001) directions. The negative component is markedly anisotropic, being greatest when the cyclotron motion is confined to a (100) plane. Two possible causes are discussed: a preferred alignment of the localized moments, such as previously indicated by Mossbauer measurements, and an anisotropic s-d exchange coupling between the electrons and the virtual bound state.Keywords
