Decrease of effective susceptibility of the superconducting material inside the nuclear magnetic resonance (NMR) probe

摘要

(57) Abstract Approaching to the sample field inside the nuclear magnetic resonance device probe by giving attenuation AC change inside the parallel magnetic field to the aforementioned superconducting material, in order that it makes the effective susceptibility of the hot superconducting material decrease which is used, hisuteriteitsuku of the type II superconductive conductor it can give manner and the device which utilize behavior. As for the said manner, loss of the resolution which it occurs from road widening of the belt which is pulled up by the discontinuity of susceptibility of the material near the sample field of the probe it is not with as for those it is especially application possible in the receiver coil which decreases the effective susceptibility of the superconducting receiver coil which makes the sensitivity where the place where it is implemented to characteristic is improved possible.
