title: Ferromagnetic behaviour of nickel contacted multiwalled carbon nanotubes.
abstract: A novel method for the contact of ferromagnetic nano-nickel onto multiwalled carbon nanotubes (MWCNTs) is proposed in this work. The process involves the decomposition of the precursor: nickel carbonyl-Ni(CO)4 into nickel and CO by laser chemical vapour deposition at 150-200 degrees C and the deposition of nano-nickel onto MWCNTs. Field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), HR (High resolution) TEM, and Raman spectroscopy were employed for the detailed analysis of the nickel contacted MWCNTs. The ferro-magnetic nature of the sample was confirmed by Super-conducting Quantum Interference Device (SQUID) analysis.
