NMR Using Earth’s Magnetic Field

Berkeley Lab Researchers Demonstrate Ultra Low-Field Nuclear Magnetic Resonance with an Optical Magnetometer

Earth’s magnetic field, a familiar directional indicator over long distances, is routinely probed in applications ranging from geology to archaeology. Now it has provided the basis for a technique which might, one day, be used to characterize the chemical composition of fluid mixtures in their native environments.
