• Co_<20>Cu_<80> binary alloy is produced by mechanical alloying. The magnetoresistance (MR) and magnetic properties in temperature range from 5K to 300K, have been investigated for the as-milled and annealed alloys. The MR for the as-millked sample measured at the temperature below 120K is not proportional to the square of magnetization M^2. However, the MR for the annealed sample changes almost following M^2 even below this temperature. With decreasing temperature, the MR ratio for the as-milled sample slightly increase and becomes a constant value of about 3% below 180K, and for the annealed sample monotonously increases and shows about 14% at 5K.
