Results of a series of synchrotron radiation scattering studies of a Pb(Mg 1/3 Nb 2/3 )O 3 (PMN) single crystal are presented. The temperature dependence of the 1:1 chemical short-range order (SRO) peaks, e.g. 1/2(115), was studied in detail from 40 to 473 K. At low temperatures, the temperature dep
