It was found that nanotubes with defects contain larger core-shell Fe/Fe3O4 particles with a higher coercive force than perfect nanotubes, but the relative proportion of such particles is 4 times smaller in defective nanotubes, all other conditions being equal (growth rate in butanol, temperature). Keywords: core-shell particles, nanocomposites, Raman spectroscopy, chemical vapor deposition, carbon nanotube fibers.
