摘要: Abstract High resolution time-of-flight neutron powder diffraction has been performed on the intermetallic compound YNi10Si2 of ThMn12 (space group I4/mmm) tetragonal structure at room temperature. Rietveld profile refinement pattern gave detailed structural parameters. The Si atoms are found to preferentially occupy 8⨍ site with some small occupancies also for both 8i and 8j sites. A minority impurity phase identified as that cubic NaZn13-type Fm 3 c) . This present investigation metalloid substitution three transition metal sublattices in this type, well previous studies, confirm atomic size enthalpy effects important determination preferential ordering.
