We have studied the effects of residual water during the deposition process and the deposition rate on the giant magnetoresistance (GMR) in Co/Cu superlattices prepared by sputtering. The magnetoresistance (MR) ratio decreases drastically with an increase in the amount of residual water and a decrease in the deposition rate. In order to understand these results, we introduce the residual water to deposition rate ratio parameter, xi, which is proportional to the exposure of the surface of the sample to residual water. It has been found that the MR and magnetic properties of the superlattices are universally expressed in terms of xi.
