PROTON NUCLEAR-MAGNETIC-RESONANCE AND H-SITE OCCUPANCY IN ZR0.5NI0.5YCUYHX METALLIC GLASSES

The aim of this paper is to reinvestigate the proton magnetic resonanc e spectra in Zr0.5Ni0.5-yCuyHx metallic glasses. Solid-echo pulse sequ ences were used to analyze the line shape. The measurements were made in the temperature range 2.2-300 K and at a frequency of 87.6 MHz. The reinvestigation of the line shape mostly at low temperatures was init iated after having realized that the splitting reported earlier on our samples was a consequence of the relatively long recovery time of our spectrometer. The present solid-echo measurements yielded simple spec tra describable by a Harper-Barnes line shape close to gaussian.
