TLDR
In this paper, the magnetostatic interactions between carbon nanotubes filled with magnetic particles have been experimentally and theoretically studied, and it has been shown that the attraction/repulsion events are predictable, and that the suspensions of magnetic nanoparticles are attractive candidates for active elements in changeable diffraction gratings, filters, and polarizers.Abstract:
The magnetostatic interactions between carbon nanotubes filled with magnetic particles have been experimentally and theoretically studied. By making nanotubes uniformly magnetized, one eliminates the attraction caused by periodicity of nanoparticles in magnetic chains. The discreteness of individual nanoparticles in the nanoneedles is not observed and these nanoneedles interact by their magnetic poles. Since the attraction/repulsion events are predictable, the suspensions of magnetic nanotubes are attractive candidates for active elements in changeable diffraction gratings, filters, and polarizers.read more
