"Recent developments in atomic and diamond magnetometers and their applications in NMR."

"A lot is going on in the magnetometry field, with new techniques sprouting that allow ever-improved sensitivity and spatial resolution. One of the latest raves is magnetometers based on color centers in diamond that consist of a substitutional nitrogen atom and a vacancy in a diamond lattice.To measure Earth’s magnetic field, an orange laser beam is directed at a layer of sodium 90 kilometers above the planet. This presentation will cover recent applications of magnetometers to nuclear magnetic resonance without magnets (!) and other magnetometer adventures ranging from the search for plant biomagnetism to measuring magnetic fields in the mesosphere using sodium laser guide stars."
