Abstract
An NMR spectrometer and method in the following three steps are performed. (1) An external magnetic field is set to H+ΔH (where 4H>0). When the detection coil made of the superconducting material is still in a normal state, a magnetic field stronger than the ultimate target static magnetic field strength Hby ΔH is applied to the detection coil. (2) The detection coil made of the superconducting material is cooled down to Tlower than its critical temperature Tto bring the coil into a superconducting state while the external magnetic field H+ΔH is applied to the detection coil. (3) The external magnetic field is lowered from H+ΔH to Hsuch that the applied external magnetic field is decreased by ΔH while the detection coil is kept in the superconducting state.
