Materials Data on Al4Fe5Rh by Materials Project

Abstract

Fe5RhAl4 is Heusler-like structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. there are three inequivalent Fe sites. In the first Fe site, Fe is bonded in a body-centered cubic geometry to four equivalent Rh and four equivalent Al atoms. All Fe–Rh bond lengths are 2.59 Å. All Fe–Al bond lengths are 2.56 Å. In the second Fe site, Fe is bonded in a body-centered cubic geometry to eight Al atoms. All Fe–Al bond lengths are 2.46 Å. In the third Fe site, Fe is bonded in a body-centered cubic geometry to eight equivalent Al atoms. All Fe–Al bond lengths are 2.52 Å. Rh is bonded in a body-centered cubic geometry to eight equivalent Fe atoms. There are two inequivalent Al sites. In the first Al site, Al is bonded in a body-centered cubic geometry to eight Fe atoms. In the second Al site, Al is bonded in a body-centered cubic geometry to eight Fe atoms.
