Nanomagnetics

Abstract

A simple and versatile chemical method is used to open tips of multiwall carbon nanotubes (MWCNTs) and fill with magnetic materials. The process so far has succeeded in opening up the tips of all MWCNTs observed, but only few of the tubes were filled. The process is being fine tuned to fill a significant number of the MWCNTs with the sought compound. In this report, we will present the transmission electron microscope, energy dispersive spectroscopy, and Moessbauer spectroscopy studies on the filled MWCNTs.
