Rensselaer Polytechnic Institute (RPI, Troy, N.Y.) researchers report that carbon nanotubes can be used to detect nanoscale magnetic fields by changing their conductance. By embedding tiny nanoparticles of magnetic cobalt into multi-walled carbon nanotubes, the researchers demonstrated that the tiny devices could enable spintronics applications, nanoscale storage devices and ultra-sensitive conductance detectors.
