Materials Data on Fe11Co5 by Materials Project

Abstract

Fe11Co5 is Tungsten-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. there are four inequivalent Fe sites. In the first Fe site, Fe is bonded in a distorted body-centered cubic geometry to three Fe and five Co atoms. All Fe–Fe bond lengths are 2.47 Å. All Fe–Co bond lengths are 2.47 Å. In the second Fe site, Fe is bonded in a distorted body-centered cubic geometry to eight equivalent Fe atoms. In the third Fe site, Fe is bonded in a distorted body-centered cubic geometry to eight equivalent Fe atoms. In the fourth Fe site, Fe is bonded in a distorted body-centered cubic geometry to eight equivalent Fe and six Co atoms. There are two shorter (2.85 Å) and four longer (2.86 Å) Fe–Co bond lengths. There are three inequivalent Co sites. In the first Co site, Co is bonded in a distorted body-centered cubic geometry to eight equivalent Fe atoms. In the second Co site, Co is bonded in a distorted body-centered cubic geometry to ten Fe atoms. In the third Co site, Co is bonded in a distorted body-centered cubic geometry to ten Fe atoms.
