Discovery of giant magnetoresistance in a fullerene-Co compound system


Magnetic Materials group (Prof. K. Takanashi’s group) discovered in collaboration with Dr. S. Sakai et al., Advanced Science Research Center, Japan Atomic Energy Agency, that a nanostructured hybrid system consisting of Co nanoparticles embedded in a fullerene-Co compound matrix showed giant magnetoresistance (GMR), suggesting that the materials including fullerene might be useful in the field of spin electronics. This result was published in Applied Physic Letters, and also introduced in Nikkan-Kogyo Shinbun on September 25, 2006.
