Abstract
We present experimental evidence for ferromagnetism in C60 polymerized under ultra-violet radiation in ambient hydrogen atmosphere. Polymerization was confirmed with measurements of the Raman peak for Ag(2) mode and of chemical shifts in 13C nuclear magnetic resonance (NMR) spectroscopy. 1H-13C cross polarization NMR spectra confirmed that some C were covalently bonded to hydrogen. This photopolymerized C60 partially bonded with H exhibited weak but discernible ferromagnetism, which may be explained with a spin-transfer mechanism.
