Crystallographic structure of ErFeO3. (a) and (b) Schematics of the crystallographic structure of perovskite ErFeO3 (EFO) from the a and c axes, respectively. The pink, grey, and yellow spheres represent Er3+, Fe2+, and O2− ions, respectively. (c) Observed (open circles) and calculated (solid line) powder X-ray diffraction patterns for the ground EFO single crystals. The blue curve represents the intensity difference between the observed and calculated patterns. The green short lines denote the Bragg positions.
