Abstract

Unique magnetic-field-induced ferromagnetism is observed in a solid of bissilylated C60 after heat treatment. The Curie temperature observed is higher than room temperature. The saturation moment is 9×10-3μB and 0.045μB per C60 molecule at 300 K and 1.9 K, respectively. Silyl substituents are confirmed to be cleaved during a heat process by means of 1H-NMR and 13C-NMR, and the electron spins left on C60 sites are responsible for the observed ferromagnetic properties.
