Testing the magnetism of polymerized fullerene

Academic Article


  • We present band structure calculations of rhombohedral C60performed in the local-spin-density approximation. Rhombohedral C60(Rh-C60)is a two-dimensional polymer of C60with trigonal topology. No magnetic solution exists for Rh-C60and energy bands with different spins are found to be identical and not split. The calculated C 2p partial density of states is compared to carbon K-edge x-ray emission and absorption spectra and shows good agreement. It is concluded that the rhombohedral distortion of C60itself cannot induce magnetic ordering in the molecular carbon. The result of magnetization measurements performed on the same Rh-C60sample corroborates this conclusion. © 2004 The American Physical Society.
