Magnetization is measured in plastically deformed alloy in the temperature range from 4.5 to 80 K.The temperature dependence of spontaneous magnetization has been analysed according to the self-consistent renormalization theory of spin fluctuation. The value of decreases from to and the Curie temperature declines from 57.8 to 50.1 K with 50% strain. The decreases in and can be explained by the introduction of the antiphase boundary, which reveals the existence of an atomically ordered structure in the Ni - Cu alloys.
