Single crystalline Co2Si nanobelts were synthesized for the first time. Temperature-dependent electrical transport studies show the Co2Si nanobelts exhibit metallic behavior with a large negative magnetoresistance over 10% at low temperature, which may be attributed to alignment of the spins in surface cobalt atoms.
