Physicists Used Graphene to Build an Extremely Tiny Magnetic Field Detector – ScienceAlert
Often it’s the most minute scientific measurements that are the most important, and researchers have developed a new, super-small device that’s capable of detecting magnetic fields even when they’re extremely faint.
Often it’s the most minute scientific measurements that are the most important, and researchers have developed a new, super-small device that’s capable of detecting magnetic fields even when they’re extremely faint.
The device, a new kind of superconducting quantum interference device (SQUID), is just 10 nanometres high, or around a thousandth of the thickness of a human hair. It’s made from two layers of graphene making it one of the smallest SQUIDs ever built separated by a very thin layer of…
