Title: Materials Data on GdErO3 by Materials Project

Abstract

ErGdO3 is Spinel-like structured and crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are five inequivalent Er3+ sites. In the first Er3+ site, Er3+ is bonded to six O2- atoms to form distorted ErO6 octahedra that share corners with three ErO6 octahedra, corners with three GdO6 octahedra, an edgeedge with one ErO6 octahedra, and edges with five GdO6 octahedra. The corner-sharing octahedra tilt angles range from 52–59°. There are a spread of Er–O bond distances ranging from 2.24–2.35 Å. In the second Er3+ site, Er3+ is bonded to six O2- atoms to form distorted ErO6 octahedra that share a cornercorner with one ErO6 octahedra, corners with five GdO6 octahedra, edges with three ErO6 octahedra, and edges with three GdO6 octahedra. The corner-sharing octahedra tilt angles range from 53–56°. There are a spread of Er–O bond distances ranging from 2.24–2.35 Å. In the third Er3+ site, Er3+ is bonded to six O2- atoms to form distorted ErO6 octahedra that share corners with two equivalent ErO6 octahedra, corners with four GdO6 octahedra, edges with two equivalent GdO6 octahedra, and edges with four ErO6 octahedra. The corner-sharing octahedra tilt angles range from 53–57°. There are four shorter (2.25 Å)more » and two longer (2.35 Å) Er–O bond lengths.
