title: The excitation of NMR transitions by the current in a sample and the proposals for its detection.
abstract: A new magnetic resonance technique for investigating conducting samples is described. NMR transitions are excited by the magnetic field of alternating current which flows across the sample. The dissipation of the energy caused by NMR transitions results in a change of the impedance of the sample. The NMR signal is detected as an associated change of the voltage drop across a sample while passing through the resonance region. It is predicted that the resonance can be detected by state-of-the-art low-noise superconducting quantum interference device (SQUID)-based NMR spectrometers. The method is believed to be useful for investigations of small-volume samples which are inaccessible by other NMR techniques.
