 note = {application/pdf, 論文(Article), The local structures around Nb and Pb in the prototypical relaxor ferroelectric Pb(Mg_1/3Nb_2/3)O_3 (PMN) were
investigated by x-ray fluorescence holography. The separate atomic images of nearest Pb around Nb revealed
acute and obtuse rhombohedral structures of the crystal unit cells. The Pb-Pb correlated images showed a local
structure of body-center-like 2a_0 × 2a_0 × 2a_0 superlattice, proving a rigid three-dimensional network structural
model combining the two kinds of rhombohedrons. The Pb atoms in the networks are positionally stable, while
the other Pb atoms are fluctuating. This superstructure and the fluctuating Pb and Nb atoms are believed to play
an important role in the relaxor behavior of PMN at the atomic level., http://journals.aps.org/prb/abstract/10.1103/PhysRevB.89.140103},
