Abstract
The structural and magnetic characterization of Lu2Fe17Hx (x=0; 3) single c rystals is presented. The host alloy crystallizes with a disordered variant of hexagonal (Th2Ni17-type P6(3)/mmc) structure, It is observed that the h ost alloy symmetry is retained upon hydrogenation. Hydrogen is found to be accommodated in the rare earth-rich octahedral position. The Neel temperatu re of the hydride Lu2Fe17H3 is increased by 35 K per hydrogen atom. The mag netization and magnetic anisotropy constant remains practically unaffected in the hydride Lu2Fe17Hx at x=3. (C) 2001 Elsevier Science B.V. All rights reserved.
