Zusammenfassung:
The influence of the (H,D) isotope substitution on the metamagnetic
transition in (Y1-xRx)Fe-2(H1-yDy)(4.2) (R=Tb, Er, x=0, 0.1, and y=0,
1) compounds has been studied by x-ray diffraction and magnetic
measurements. All these compounds crystallize in the same monoclinic
structure with larger cell volume for the hydrides compared to the
deuterides. The metamagnetic transition temperature T-M is not only
field dependent but also strongly related to the volume change. The
increase of T-M is more strongly related to the (H,D) isotope
substitution than by the rare earth substitution on the Y site. (C)
