We have investigated the effect of Mn doping into Cu layers on the interlayer coupling in Co/Cu multilayers and found a partial change of the interlayer coupling from ferromagnetic to antiferromagnetic or vice versa with decreasing temperature. The change of the interlayer coupling occurs around a critical temperature which depends on both the Cu(Mn) layer thickness and Mn concentration. As an origin of the change of the interlayer coupling, a cooperative interaction among the Co layers and the Mn ions is discussed in correlation with a spin-glass-like state.
