Abstract:
1. A nuclear magnetic resonance apparatus comprising: a means for generating a predetermined uniform magnetic field; and a probe that is disposed in the magnetic field and into and from which a sample tube holding a sample to be measured can be inserted and withdrawn, wherein the magnetic field generating means comprises two split superconducting magnets, and the probe is inserted in the direction perpendicular to or parallel with the direction of the magnetic field generated by the superconducting magnets, wherein the probe is provided with: a layered structure of the plurality of substrates having a one-turn coil, obtained by processing a superconducting thin film, formed on the surfaces thereof, and spacer substrates provided between the substrates; and a probe coil formed in solenoid type by connecting the coils on the plurality of substrates, obtained by processing a superconducting thin film, in serial, parallel, or serial parallel, and wherein the spacer substrates are cooled directly or indirectly by a cold head coupled with a cryo cooling system.
