Cole, Jacqueline M. and Hannon, Alex C. and Martin, Richard A. and Newport, Robert J. (2006) Direct observation of R...R distances in rare-earth (R) phosphate glasses by magnetic difference neutron diffraction. Physical Review B: Condensed Matter and Materials Physics, 73 (10).

A magnetic difference neutron diffraction study of a rare-earth (Tb) phosphate glass has revealed exclusively the Tb...Tb distances. The difference between data taken with and without an applied magnetic field of 4 T shows Tb...Tb pairwise atomic correlations at 3.9 and 6.4 A, respectively, with relative coordination numbers of 1:14. The first distance arises when two Tb3+ ions share a common oxygen neighbor, and indicates a clustering of rare-earth ions. The second distance arises when two Tb3+ ions are coordinated to different oxygens in the same PO4 group, in a near-linear arrangement.
