本文研究了新型金属间化合物Fe_(23)CB_(6)的相稳定性和占位性。Fe_(23)CB_(6)可能以Cr_(23)C_(6)为原型结构,C原子位于4a位。计算的晶格常数与文献报道的结果一致。计算了Fe_(22)NiB_6、Fe_(23)C_6、Fe_(23)B_6和Fe_(23)CB_6化合物的磁矩。此外,我们还计算了Fe_(23)C_6、Fe_(23)B_6和Fe_(23)CB_6的全声子态密度和部分声子态密度。通过对反转势的分析,定性地解释了不同原子对振动模的贡献。
The new intermetallics Fe23CB6have been studied to ascertain the effect of ternary element C on the phase stability and site preference. Fe23CB6may form with Cr23C6prototype structure, and the carbons atoms are positioned at 4a sites. The calculated lattice constants are found to agree with report in literatures. We have calculated the magnetic moments of Fe22NiB6, Fe23C6, Fe23B6and Fe23CB6compounds. Furthermore, the total and partial phonon densities of states are evaluated first for Fe23C6, Fe23B6and Fe23CB6. The analysis of the inverted potentials explains qualitatively the contributions of different atoms to the vibrational modes.
