Abstract The electrical resistivity of paramagnetic CuNi alloys in composition range between 30 and 42 at.-% Ni due to spinflip scattering of conduction electrons from individual and coupled spin-clusters was studied by using the disordered spin-cluster model Together with the ρ_L(T) phonon contribution, the total resistivity can be written as: ρ=ρ_L(T)+ρ_0(0)-nρ_1lgT+A n~2/T The resistance minima that was observed in the experiments was explained by using the results.
