Rensselaer Polytechnic Institute researchers now believe that carbon nanotubes can be used to detect nanoscale magnetic states (Spin) by changing their conductance. They demonstrated the change by embedding tiny nanoparticles of magnetic cobalt into multi-walled carbon nanotubes.

The researchers furthermore claim that their findings could enable spintronics applications, nanoscale storage devices and ultra-sensitive conductance detectors.
