摘要：
181Ta PAC and electron diffraction experiments on ZrMn2 show that the presence of Hf in substitution for Zr at a concentration of 2 at. % can be responsible for distortions from the C14 structure of this intermetallic alloy. The PAC spectra recorded between RT and 50K for the hydride Zr0.98 Hf0.02 Mn2H3.2 display two successive modifications in the temperature regions 180-150K and 100-50K. In the present state of PAC data analysis, we are not able to claim that such modifications are related to the low-temperature magnetic properties of ZrMn2 hydrides. © 1990 J.C.
