Abstract: The magnetic properties of Cu_{1 - x}Co_{x} alloy films prepared by electrodeposition technique were investigated by Alternating Gradient Force Magnetometer. The magnetization curves of Cu_{0.94}Co_{0.06}, Cu_{0.87}Co_{0.13} and Cu_{0.74}Co_{0.26} films were easily saturated while the other Cu_{1 - x}Co_{x} samples with x= 0.17, 0.19 and 0.21 had more inclined magnetization curves. The saturation magnetization value of Cu_{1 - x}Co_{x} film increased with increasing Co content in the film. The minimum values of the ratio of remanence to magnetization and the coercive field were determined in the Cu_{0.81}Co_{0.19} alloy film among the others. The ferromagnetic order in the Cu_{1 - x}Co_{x} films was between 2.5-29%.
