Abstract: The dc joule heating technique has been used to produce giant magnetoresistance (GMR) Co5Cu95 granular alloys. At T = 10 K, GMR as large as 28.5% has been observed in the as-quenched sample annealed with I = 6 A in a magnetic field up to 30 kOe. At room temperature, the joule-heated samples show higher GMR in comparison with that annealed by the conventional method.
