  It is shown that polycrystalline fullerene thin films on hydrogen passivated
Si(111) substrates irradiated by 2 MeV protons displays ferromagnetic-like
behavior at 5 K. At 300 K both the pristine and the irradiated film show
diamagnetic behavior. Magnetization data in the temperature range 2 - 300 K, in
1 Tesla applied field, for the irradiated film shows much stronger temperature
dependence compared to the pristine film. Possible origin of ferromagnetic-like
signals in the irradiated films are discussed.
