|Title:||Improved Giant Magnetoresistance In Magnetic Granular Co5 Cu95 Alloys By Direct-current Joule Heating|
|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=6A 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. © 1996 Springer-Verlag.|
