Abstract: Nickel-phosphorus (EN) deposited multi-walled carbon nanotubes (MWCNTs) were prepared using an electroless plating technique. The D.C and A.C magnetic behavior of the composites showed that pre-acid treatment of the MWCNTs prior to electroless deposition greatly enhanced the magnetic susceptibility at 5oK producing a composite with antiferromagnetic correlations and a superparamagnetic transition at 65.5 K. Raman scattering analysis suggests that there is no direct interaction of the nickel-phosphorus deposit and the MWCNTs.
