Abstract
We report preliminary measurements of the magnetoresistance in sputtered GdCo3 thin films from 4.2 to 100 K and in magnetic fields up to 6 T. Beyond technical saturation, the magnetoresistance is positive, varies linearly with the applied field and is nearly temperature independent. A possible contribution from electron interactions is discussed.
