Abstract

We have performed elastic diffuse neutron scattering studies on the relaxor Pb(Mg $_{1/3}$ Nb $_{2/3}$ )O $_3$ (PMN). The measured intensity distribution near a (100) Bragg peak in the (hk0) scattering plane assumes the shape of a butterfly with extended intensity in the (110) and (1 $\bar{1}$ 0) directions. The temperature dependence of the diffuse scattering shows that both the size of the polar nanoregions (PNR) and the integrated diffuse intensity increase with cooling even for temperatures below the Curie temperature $T_C \sim 213$ K.
