Metastable Co x Cu 100‐ x ( x = 5, 10, 15, 20) alloys have been annealed at increasing temperatures in order to study the evolution of the Co cluster and its relation with the magnetotransport properties. The structure was investigated by on the Co K‐edge as a function of composition and annealing temperature. An anomalous trend in the structural evolution has been evidenced and related to the peculiar features observed in the magnetotransport properties.
