Abstract:
1. Nuclear magnetic resonance equipment comprising: a superconducting magnet divided in halves for generating a predetermined uniform magnetic field; and a probe coil for transmitting a radio frequency signal at a predetermined resonance frequency in the direction orthogonal to the direction of said magnetic field to a sample disposed in magnetic fields of the superconducting magnet and/or for receiving a free induction decay (FID) signal, wherein a coil part as one of units constructing said probe coil is disposed so that a surface of a superconducting thin film formed on a donut plate-type substrate becomes parallel with said uniform magnetic field, a part in the superconducting thin film formed on said donut plate-type substrate is cut off in the radial direction, a capacitor having a stack structure of a normal metal electrode and the superconducting thin film sandwiching an insulator is formed at each of both ends of the cut part, the coil part as one of units constructing said probe coil is electrically connected to the normal metal lead via the normal metal electrode of said capacitor, and the probe coil is formed by connecting the plurality of coil parts in series, in parallel, or both in series and in parallel.
