Abstract
A nuclear magnetic resonance apparatus including: a cup-shaped high-temperature superconductor having a hollow cylindrical shape or portion cooled to not more than a superconducting transition temperature in a vacuum insulating container and a detection coil for detecting an NMR signal of a material to be measured inserted into the hollow cylindrical portion of the high-temperature superconductor. The high-temperature superconductor is magnetized in an axial direction, a static magnetic field is thereby generated in the hollow cylindrical portion in a cylinder axial direction, and the NMR signal of a material is detected by the detection coil and the existing spectrometer. A strong static magnetic field comparable to a conventional superconducting magnet is formed without using a refrigerant (liquid helium) essential for operating the conventional superconducting magnet, and a strength distribution of the static magnetic field is homogeneous.
