摘要：

High-resolution neutron powder diffraction studies were performed on several compounds of the type YFe12-xAlx (x=8, 7, 6). The authors observed a strong preferential site occupation of Fe on one of the three non-equivalent transition metal sites of the hMn12-type structure. In particular the 8f site is found to be markedly populated by Fe atoms, while there is a strong preference of Al for the 8i site.
