| Abstract: | Hydrogen absorption by the intermetallic compounds Ti2(Ni,Co) and Ti2(Ni,Fe) with Ti2Ni-structure (O

-Fd3m) is accompanied by an increase of the volume of the unit cell without any structural change, while the maximum value of absorbed hydrogen is practically independent of the alloy composition. By taking up hydrogen, the intermetallic compounds, showingPauli spin paramagnetism with complex temperature dependence, become either temperature independent paramagnetic hydrides of Ti2(Ni,Co)] or strongly temperature dependent paramagnetic, following a modifiedCurie-Weiss-Law hydrides of Ti2(Ni,Fe)], respectively.Herrn Prof. Dr.H.
