We were able to distinctively characterize the Fe catalyst particle distribution in multiwalled carbon nanotubes (MWNTs) synthesized by vapor-phase growth at 950 degrees C by means of macroscopic SQUID measurements and Raman analysis. The magnetic properties of Fe particles included the MWNTs are shown to depend on the formation of MWNTs. The size and number of Fe particles included in MWNTs are discussed in terms of the change of average magnetic moment, the coercive field, and remanent magnetization of Fe particles with changing Fe concentration.
