A (63)Cu and (65)Cu NMR Study on an Amorphous Ni-Cu-P Alloy

摘要

The Cu-03 and Cu-65 NMR spectra were recorded on an amorphous Ni Cu P alloy using the points by point spin echo technique, and the spin lattice relaxation times, were measured by the 180 deg pulse spin each and the saturation comb spin echo sequences. The results were compared with the corresponding parameters of the 31 spectrum. The quadrupole broadening is the dominant factor in the NMR spectra of both Cu isotope and the Korringa-type mechanism is responsible for the nuclear spin lattice relaxation.
