AbstractAbstract
[en] Two different hydrides of the C15 Laves phase intermetallic ErFe2 are considered. For ErFe2 H3.65, x-ray analyses showed the presence of an expanded C15 cubic phase and lower symmetry phase. The 57Fe mean saturated hyperfine field is 20% larger than in ErFe2 and the 166Er hyperfine field is 15% smaller. These results coupled with previous measurements of the net moment imply that the Er--Fe coupling is not antiparallel in this hydride. For ErFe2 H4.12, only a structural phase consistent with trigonal lattice was detected. The Moessbauer results indicate a magnetic transition temperature between 1.7 K and 4.2 K and a drastic reduction of the Fe moment in this hydride
