Abstract: The anomalous Hall effect of wires patterned from ðCo90Fe10=PtÞn multilayers, with 10 n 50, is used to determine the magnetization process in a small volume of maze domains. Time-independent 1=f noise appears in samples with a quality factor Q<1 at points on the hysteresis loop where the magnetization reverses continuously. The magnetic noise is associated with reversible excursions of segments of a domain wall 100 nm long. Barkhausen jumps are observed close to either the switching field or the saturation field where the noise power spectrum varies as 1=f1:7, and its magnitude decays with time.
