a XRD pattern of the multi wall carbon nanotubes (mCNTs). b Magnetization curve up to 13 kOe at room temperature of the (mCNTs). Inset is enlargement of the hysteresis loop at low applied fields. c Mossbauer spectrum for the mCNTs recorded at room temperature. d UPS valence band spectra of the mCNTs and few layers of graphene. Inset is the density of state (DOS) at vicinity of Fermi level
