Abstract
The structure of Yo(0.5)Er(0.5)AlO(3) was refined from powder diffract ion data (powder diffractometer HZG, Cu K alpha): GbFeO(3) type struct ure, space group Pbnm, a = 5.17011(5) Angstrom, b = 5.32872(5) Angstro m, c = 7.36274(8) Angstrom, Z = 4, R = 0.1042 using the isotropic appr oximation for thermal parameters. The shortest interatomic distances a re: Al-O 1.898(6) Angstrom, Y(Er)-O 2.221(8) Angstrom, Y(Er)-Al 3.0094 (7) Angstrom, Y(Er)-Y(Er) 3.628(2) Angstrom, Al-Al3.6874(1) Angstrom, O-O 2.682(9) Angstrom. The coordination numbers for the atoms are: ytt rium(erbium) 8, aluminum 6, O-1 12, O-2 13.
