New Nanomagnets Can Sniff Out Magnetism, Make Nanomemory
Scientists develop new nanotube structures to act as mini-magnet detectors
The new process involves inserting cobalt nanoclusters between 1 nm and 10 nm into a single multi-walled carbon nanotube. As the carbon nanotube is an excellent conductor, it is also sensitive to magnetic activity, such as that of the cobalt nanoclusters. The result is a magnetic nanomaterial, which also can sense electrically other magnetic nanofields.
