摘要：

In-beam Mossbauer spectra of Mn-57 implanted into LiAlH4 were measured at different temperatures between 17 and 300 K. The Mossbauer spectrum measured at 17 K showed two sets of doublets, which were assigned to Fe-57 atoms at substitutional sites at Al3+ and Li+ sites. The Debye temperatures theta(M) for the Fe-57 atoms at Al3+-substituted and Li+-substituted sites were estimated to be 194 K and 117 K, respectively. The assignments were confirmed by density functional theory calculations.
