Finding of anomalously large magnetoresitance effect in fullerene-cobalt thin filmsSep. 22, 2006Japan Atomic Energy Agency, in collaboration with Tohoku University, has revealed that the nanometer scaled hybrid films of Co nanoparticle and C60-Co compound show a large tunnel magnetoresistance (MR) effect whose MR ratio attains 80% depending on the applied bias voltage (see ref. [1] and [2] for the details). This study was done by Dr. Seiji Sakai (JAEA), Dr. Kay Yakushiji (Tohoku University) and colleagues. The observed MR ratio is, to our knowledge, the highest one in nanogranular type thin films including inorganic systems. The present finding could be an important milestone for the development of organic molecule-based spintronics (organic spintronics). [1] S. Sakai, K. Yakushiji, S. Mitani, K. Takanashi, H.
