Giant magnetoresistance in Co-Al2O3 granular films prepared by self-organized growth

Co-Al2O3 granular films with a narrow distribution in cluster size of Co clusters embedded in Al2O3 matrix were prepared by sequential deposition based on self-organized growth. Resistivity dependence of giant magnetoresistance (GMR) was studied. The GMR takes a maximum of 5.2% at room temperature a...
