We examined the local structure of hole-doped hexagonal multiferroic YMn0.9Zn0.1O3 using x-ray absorption fine structure analysis. It was shown that Zn atoms substitute Mn atoms while keeping the bipyramidal oxygen coordination unchanged. Comparative study with pure YMnO3 further showed that the Mn-O bond length splitting is diminished by approximately 0.05 Å, suggesting an enhanced orbital hybridization in the planar Mn-O bonds due to additional Mn3+ → O2- electron transfer near the Zn2+ ions. It is a conclusive experimental evidence that Zn doping indeed introduces hole doping on to the two dimensional Mn sublattice of the hexagonal multiferroic YMnO 3.
