  • Abstract
    A high-stability constant current source has been developed using the nuclear magnetic resonance (NMR) field-frequency lock technique. The current is locked to the NMR frequency via the magnetic field of the electromagnet which has a highly stable coil constant. The current of 1 A has been stabilized to better than 0.2 ppm/h.
