摘要

The influence of interstitial hydrogen or carbon on the crystal structure of LaFe_(11.5)Si_(1.5)H_ ? (? = 0,1.2, and 2) and LaFe_(11.5)Si_(1.5)C_ ? (? = 0,0.1,0.2,0.3,0.4, and 0.5) has been investigated based on the Rietveld analyses of powder X-ray diffraction spectra. Effects of Ce substitution for La are also studied for comparison. The incorporation of interstitial atoms causes a lattice expansion of the compounds while leaves the structural symmetry unchanged. Accompanying the lattice expansion, Fe-Fe bond exhibits a concomitant variation. Four of the five Fe-Fe bonds show a tendency to expansion.
