  • Beschreibung: AbstractThe systematic magnetic and structural properties of as‐prepared, “Fe” catalyst based multiwalled carbon nanotubes (MWCNTs), and chemically modified MWCNTs were studied. The structural characterization by means of transmission electron microscopy, X‐ray diffraction, and Raman spectroscopy was performed. DC magnetization up to 9 T was studied. We examined the influence of chemical treatment (purification procedure) on the magnetic properties of MWCNT's. The significant changes in the saturation magnetization after chemical treatment were observed. However, we noticed high magnetic coercivity values for as‐prepared as well as chemically modified samples.
