Abstract

C60-Co nano-composites, in which Co nano-particles are embedded in C60 molecules, have been fabricated and a magnetoresistance (MR) ratio of 8% has been observed at T = 4.2 K. In addition, we have succeeded in observing a clear MR curve even at room temperature (RT). The MR effect is ascribed to magnetization of the Co nano-particles and spin-dependent transport in C60 molecules. This study directly indicates that RT operation of molecular spin devices can be realized. J
