PMR SPECTRUM, PROTON SPIN RELAXATION AND DIFFUSION IN ZR0.5(CUXNI1-X)0.5H1 METALLIC GLASSES

Proton magnetic resonance spectrum, laboratory and rotating frame spin -lattice relaxation times were measured on Zr0.5(CuxNi1-x)0.5H1 metall ic glass samples at x = 0 and 0.3 compositions, at different temperatu res and frequencies. The experimental data were compiled by a BRUKER S XP and a SMIS NMR spectrometer. Samples prepared by melt-spinning in v acuum and checked by X-ray diffraction were used, and they were charge d with hydrogen from gas. Conclusions concerning the hydrogen sites, t he hydrogen diffusion and cross-relaxation were drawn.
