A pulsed-field-gradient NMR study of hydrogen diffusion in the Laves-phase compounds ZrCr2Hx

Abstract
Hydrogen diffusivities D in C14-ZrCr2H0.4 and C15-ZrCr2Hx (0.22Cr2) sites occupied by hydrogen in these compounds. A diffusion model that considers jumps between next-nearest-neighbour (Zr2Cr2) sites via metastable (ZrCr3) sites is discussed.
