The effect of systematic Au doping on the onset of enhanced 1/f noise in the electrical resistance fluctuations of CuMn spin-glass alloys is reported. The purpose of the Au doping is to add a unidirectional anisotropy to that already present from the Mn in Cu. We find that the ratio of the noise onset temperature to the spin-glass temperature is not affected by the increase in anisotropy.
