Local Distortion Induced Metal-to-Insulator Phase Transition in PrRu $_{4}$ P $_{12}$

D. Cao, R. H. Heffner, F. Bridges +4

Extended X-ray Absorption Fine Structure (EXAFS) experiments have been carried out on PrRu $_{4}$ P $_{12}$ and PrOs $_{4}$ P $_{12}$ to study the metal-to-insulator (MI) phase transition in…

Lattice dynamics and correlated atomic motion from the atomic pair distribution function

I. -K. Jeong, R. H. Heffner, M. J. Graf +1

The mean-square relative displacements (MSRD) of atomic pair motions in crystals are studied as a function of pair distance and temperature using the atomic pair distribution funct…

Limits on phonon information extracted from neutron pair-density functions

Matthias J. Graf, Il-Kyoung Jeong, Daniel L. Starr +1

We explore the possibility of extracting information about lattice dynamics in simple crystal structures from the neutron pair-density function (PDF) through inverse data analysis.…
