(Color online) (a) Zn K-edge XANES of YMn0.9Zn0.1O3 and the reference spectra of ZnO6 (from rocksalt ZnO (Ref. 11)), ZnO5 (from a Zn-substituted phthalate dioxygenase (Ref. 10)), and ZnO4 (from wurtzite ZnO) coordinations. (b) Y K- and (c) Mn K-edge XANES of YMn0.9Zn0.1O3 and YMnO3.

(Color online) FT EXAFS of YMn0.9Zn0.1O3 and YMnO3 at the (a) Y K-edge, (b) Mn K-edge, and (c) Zn K-edge. A change in the overall lineshape is observed for the Mn-O bonds, not the Y-O bonds.

FIG. 3.

(Color online) The experimental Mn K-edge FT EXAFS spectra of YMn0.9Zn0.1O3 and YMnO3 are enlarged to focus on the changes in the MnO5 coordination. The simulated EXAFS results are shown with various Mn-OP bond lengths while fixing the Mn-OA bond length at the value of YMnO3 (1.86 Å). The simulated spectra fit the spectrum of YMn0.9Zn0.1O3 best at a Mn-OP bond length of 2.01 Å, which is diminished by approximately 0.05 Å from that of YMnO3 (2.06 Å). The inset figure describes the corresponding structural change due to the Zn doping.
