论文摘要
Sigma-phase FE0.525CR0.455NI0.020合金通过Mössbauer光谱仪研究在5-293 K的温度范围内进行。<cs>的平均中心移动，<cs>，根据记录的Mössbauer光谱确定，在温度范围内显示了Debye模型的偏离。 50 k，即样品的磁态。偏差显然是由于磁性对所研究样品晶格动力学的影响。根据Debye模型，在顺磁性阶段对<cs> -DATA的分析得出的Debye温度的值为437（7）K。
Sigma-phase Fe0.525Cr0.455Ni0.020 alloy was studied by means of Mössbauer spectrometry in the temperature range of 5-293 K. The average center shift, <CS>, determined from the recorded Mössbauer spectra was shown to significantly deviate from the Debye model in the temperature range below ca. 50 K i.e. in the magnetic state of the sample. The deviation is obviously due to the effect of magnetism on the lattice dynamics of the studied sample. Analysis of the <CS>-data in the paramagnetic phase in terms of the Debye model yielded the value of 437(7) K for the Debye temperature.
