A highly sensitive diamond quantum magnetometer utilizing nitrogen-vacancy centers can achieve millimeter-scale resolution magnetoencephalography (MEG). The novel magnetometer, based on ...

Important instruments for neuroscience and medical diagnostics, optically pumped magnetometers measure responses of polarized atoms to produce information about the low-frequency external field. They ...

Physicist have captured a Bose Einstein condensate within a laser beam to made a device that maps magnetic fields more precisely than ever before. The magnetometer relies on the fact that the spins of ...

To measure the Earth's magnetic field, an orange laser beam is directed at a layer of sodium 90 kilometers above the Earth. The beam is pulsed at a rate determined by the local magnetic field in order ...

Researchers at the National Institute of Standards and Technology (NIST) have developed a new type of magnetometer–or magnetic-field detector–that rivals the sensitivity of its predecessors but is ...
