On December 8, Rensiler Institute of Technology announced that researchers have successfully embedded cobalt nanostructured clusters with a diameter ranging from 1 nm to 10 nm within multi-layer carbon nanotubes, developing a novel approach for detecting the magnetic characteristics of nanomaterials.
After a succession of experiments, the researchers ultimately ascertained that the hybrid structure they obtained, composed of cobalt nanomaterials and carbon nanotubes, possesses adequate conductivity sensitivity to detect the magnetic behavior of magnetic materials as minute as cobalt nanostructures. It is reported that this marks the first occasion where researchers have demonstrated the utilization of independent carbon nanotubes to detect the magnetic field of minuscule magnetic materials. The report is featured in the latest issue of Nano Letters.
When common materials are downsized to the nanometer scale, they exhibit interesting and beneficial new traits. A significant challenge for nanotechnology is to comprehend these new attributes, namely, alterations in properties. The magnetic variation of magnetic materials is closely associated with the size alteration of the material itself. The difficulty in measuring the magnetic change of nanomaterials in the past has impacted the in-depth study of this subject.
"Since the cobalt nanostructured clusters are embedded within the carbon nanotubes rather than on their surface in our hybrid material, they do not cause electron scattering and thus do not affect the conduction properties of the carbon nanotube host." "Basically, this hybrid nanostructure pertains to a new category of magnetic materials," said lead researcher Swasdik Carr, an assistant professor in the Department of Physics, Applied Physics and Astronomy at the Rensiler Institute of Technology.
Associate Professor Saroji Nayak believes that this new hybrid nanostructure not only pioneers new methods for fundamental and applied physics research but also holds the promise of assisting people in leveraging magnetic degrees of freedom, paving the way for enhancing the electrical functionality of carbon nanotubes. Potential applications of this hybrid structure encompass novel nanoscale conductive sensors, new electronic memory devices, spintronic devices, and body-directed drug micro-delivery components."
