|Title:||57fe Mössbauer Investigation Of The Ternary Hydride Pd3fehx|
da Costa Jr. M.I.

|Abstract:||Ordered alloys of Pd3Fe are shown to readily absorbe hydrogen through electrolytic loading. The resultant ternary hydride phase is observed to retain the fcc structure of Pd3Fe with approximately the same lattice constant. The 57Fe hyperfine field determined by Mössbauer spectroscopy is found to be 30% smaller in the hydride compared to Pd3Fe. The reduction appears to be associated with a perturbation of the Pd moment by hydrogen. The results suggest the occupation of one type of interstitial site in the structure. The absence of the site in disordered Pd3Fe would explain the much smaller hydrogen capacity observed for this alloy. © 1981.|
