Abstract:
Single crystalline Co(2)Si nanobelts were synthesized for the first time. Temperature-dependent electrical transport studies show the Co(2)Si 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.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
