Abstract

X-ray and neutron scattering studies of the lead-based family of perovskite relaxors Pb(Zn1/3Nb2/3)O-3-xPbTiO(3) (PZN-xPT) and Pb(Mg1/3Nb2/3)O-3-xPbTiO(3) (PMN-xPT) have documented a highly unusual situation in which the near-surface region of a single crystal can exhibit a structure that is different from that of the bulk when cooled to low temperatures. The near-surface region, or "skin" can also display critical behavior that is absent in the crystal interior, as well as a significantly different lattice spacing. By varying the incident photon energy, and thus the effective penetration depth, X-ray measurements indicate a skin thickness of order 10-50 mu m for PZN-xPT samples with 0
