Abstract
Provided is a nuclear magnetic resonance probe coil that is included in a nuclear magnetic resonance apparatus in which the direction of a static magnetic field is horizontal and that can highly sensitively measure multiple nuclear species. A nuclear magnetic resonance apparatus includes a unit that horizontally applies a static magnetic field, a unit that vertically moves a specimen to a predetermined position in the apparatus, and a probe including in the distal part thereof a probe coil that applies a radiofrequency signal to the specimen and that detects a signal produced by the specimen. The probe coil includes multiple pairs of superconducting thin-film rings formed on respective substrates that are disposed in parallel with the static magnetic field while being separated from each other by a predetermined distance, a detection loop that detects a signal received by the superconducting thin-film rings, and a transmission coil that applies the radiofrequency signal to the specimen and that has the normal thereto extended horizontally.
