Crystal structure and magnetic properties were studied on a single crystal of HoFe6Al6H and compared
with those of the parent HoFe6Al6compound with a tetragonal crystal structure of the ThMn12 type.
Hydrogenation leads to a 1% volume expansion. HoFe6Al6is a ferrimagnet with exact compensation of
the Ho and Fe sublattices magnetizations at low temperatures. Both the hydride and the parent com-pound display a high magnetic anisotropy of the easy-plane type, a noticeable anisotropy exists also within the easy plane with the [110] axis as the easy magnetization direction. The hydrogenation in-creases slightly (from 10 to 10.45mB) the magnetic moment of the Fe sublattice as a result of ...
