Co-Cu alloys containing a nanoscale lamellar structure with a spacing of 3 nm were produced by electrodeposition, and the effects of annealing on the ferromagnetic properties of the electrodeposited Co-Cu alloys were investigated at room temperature. Both the saturation magnetization and the coercivity were decreased by annealing. This is related to a change in the lamellar structure upon annealing. It is suggested that in the d6-dependence range of coercivity, the lamellar boundaries play a different role from the grain boundaries.
