ABSTRACT:
It is an object of the invention to provide, in a nuclear magnetic resonance spectrometer wherein the direction of the static magnetic field is the horizontal direction, a nuclear magnetic resonance probe coil having a highly uniform magnetic field, which can measure at high sensitivity. The present invention, by selecting the design and shapes of the materials forming the probe coil with a view to suppressing disorder in the magnetic field distribution, and using superconducting thin film coils formed on hollow circular substrates to form a receiver coil and coil support materials having curved surfaces, provides a nuclear magnetic resonance spectrometer of high sensitivity that can improve uniformity of a magnetic field.
