Abstract
We have studied the influence of RF deposition power on magnetization and g iant magnetoresistance (GMR) in sputtered Co26Cu74 granular films, in order to increase GMR of as-deposited samples. M(H) measurements are fitted with superparamagnetic and ferromagnetic components and the cluster size inferr ed. Room temperature magnetoresistance as high as 8% (minimum cluster radiu s similar to 1.9 nm) was achieved with maximum RF power. (C) 1999 Elsevier Science B.V. All rights reserved.
