Materials Data on HoEr by Materials Project

Abstract

ErHo is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Er is bonded to six equivalent Er and six equivalent Ho atoms to form ErHo6Er6 cuboctahedra that share corners with eighteen equivalent ErHo6Er6 cuboctahedra, edges with six equivalent ErHo6Er6 cuboctahedra, edges with twelve equivalent HoHo6Er6 cuboctahedra, faces with eight equivalent ErHo6Er6 cuboctahedra, and faces with twelve equivalent HoHo6Er6 cuboctahedra. All Er–Er bond lengths are 3.57 Å. All Er–Ho bond lengths are 3.51 Å.
