Abstract
Pb Lm-edge absorption spectra of ordered and disordered Pb(In0.5Nb0.5)O3 (PIN) were analyzed. The absorption edges of both the ordered and disordered PIN were shifted depending on the thermal condition of post-annealing. A clear edge shift was observed between the ordered and disordered PIN crystals. The local environments of the Pb atoms were different in these PIN crystals. The edge shift can be interpreted by introducing disarrangement of B-site atoms. Disordering of B-site atoms did not influence the environment of B-site atoms though was in Pb environment.
