The Hall effect has been measured in Au-Ni, Cu-Ni, Au-Ag, and Cu-Au solid solutions at 80° and 300°K as a function of composition. The apparent number of conduction electrons is not linear with composition in the Au-Ag and Au-Cu alloys, and it is proposed that this effect is caused by the presence of diffuse Brillouin zone boundaries which arise from the short-range order.
