In-beam Mössbauer spectra of ⁵⁷Mn implanted into LiAlH₄ were measured at different temperatures between 17 and 300 K. The Mössbauer spectrum measured at 17 K showed two sets of doublets, which were assigned to ⁵⁷Fe atoms at substitutional sites at Al³⁺ and Li⁺ sites. The Debye temperatures θ_M for the ⁵⁷Fe 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.

氢化铝锂中注入的⁵⁷ Mn的束内Mössbauer光谱

在17和300 K之间的不同温度下测量了植入LiAlH ₄中的⁵⁷ Mn的束内Mössbauer光谱。在17 K下测得的Mössbauer光谱显示了两组双峰，这些双峰被分配给Al ³⁺处的^57个Fe原子。和Li ⁺网站。德拜温度θ_中号为⁵⁷个的Al Fe原子³⁺取代的和Li ⁺取代的位点被估计为分别194 K和117 K，。分配通过密度泛函理论计算得到证实。
