Patent ID: 7352186

Claim:
A nuclear magnetic resonance apparatus comprising at least: a means for horizontally applying a static magnetic field; a means for vertically moving a specimen to a predetermined position in the apparatus; a probe including in the distal part thereof a transmission coil that applies a radiofrequency signal to the specimen; and a reception coil that detects a signal produced by the sample, wherein the reception coil includes: a pair of substrates having respective superconducting thin-film rings, each of which includes an interdigital capacitor, formed on the surfaces thereof; a spacer separating the superconducting thin-film rings from each other by a predetermined inter-plane distance; and a detection loop that is magnetically coupled to the superconducting thin-film rings; the normals to the planes containing the respective superconducting thin-film rings are extended vertically; and the normal to the plane containing the transmission coil is extended horizontally, and the transmission coil bears a predetermined positional relationship to the reception coil.
