      magnetic nanoparticles.

AB  - The alignment of multiwalled carbon nanotubes (MWNTs) has been accomplished 
      through deposition of uniform layers of magnetite/maghemite nanoparticles 
      (diameter = 6-10 nm) and use of an external magnetic field. The coating of CNTs 
      with magnetic nanoparticles was performed by combining the polymer wrapping and 
      layer-by-layer (LbL) assembly techniques. The particle-coated MWNTs are 
      superparamagnetic and can be aligned at room temperature on any substrate by 
      deposition from an aqueous solution in an external field B = 0.2 T. The volume 
      magnetization of the particle coated MWNTs is found to be enhanced by 17% 
      compared to the pure particles in a powder indicating that either the adsorption 
      process onto the CNTs changes the particle magnetization, or the MWNTs carry an 
      intrinsic magnetization due to remaining Ni used as a catalyst for the growth 
      process.
