Ultra-sensitive Magnetic Microscopy with an Optically Pumped Magnetometer. [PDF]
Sci Rep, 2016 AbstractOptically pumped magnetometers (OPMs) based on lasers and alkali-metal vapor cells are currently the most sensitive non-cryogenic magnetic field sensors. Many applications in neuroscience and other fields require high-resolution, high-sensitivity magnetic microscopic measurements. In order to meet this demand we combined a cm-size spin-exchange
