Abstract
The intermetallic compound Sc is able to absorb large quantities of hydrogen gas without a change in crystal structure. The ternary hydride has the composition Sc . Its lattice constants are Å and Å (C14 type). By means of magnetic measurements we found that the moment per Fe atom changes from to . Using Mössbauer-effect spectroscopy we observed that an increase of the same magnitude (about 60%) also occurs in the hyperfine splitting. On the other hand, only a rather small change in isomer shift was observed to accompany the hydrogen absorption. Arguments are presented that it is difficult to explain the moment change in terms of a simple -band picture and charge-transfer effects.
