The research team — including Anibal Ramirez - Cuesta, Luke Daemen, and Yongqiang Cheng of Oak Ridge National Laboratory, as well as Timothy Jenkins and Craig Brown of the National Institute of Standards and Technology — used spectroscopic tools, including the state - of - the - art
inelastic neutron spectrometer called VISION at the Spallation Neutron Source, to examine the atomic - level dynamics of a special kind of molecular structure called a clathrate.
His research focuses on the use of elastic and
inelastic neutron scattering to elucidate complex behavior in materials exhibiting emergent phenomena.
This single crystal,
inelastic neutron scattering work, carried out from 2008 to 2012, was among the first to fully characterize a four dimensional data set of S (Q, E)(three Q dimensions, one energy dimension) to fit the high magnetic field spin excitation spectrum to linear spin wave theory.
A multi-partner study published today in Nature Communications has addressed phonon lifetime measurement challenges using
inelastic neutron scattering (INS) and neutron resonant spin - echo (NRSE) experiments conducted at the Institut Laue Langevin (ILL) in Grenoble, and Laboratoire Léon Brillouin (LLB) Saclay, France.
IBS scientists measured the atomic and molecular motion of (Y, Lu) MnO3 crystals by
inelastic neutron scattering experiments and also derived a new theoretical model to explain what they observed experimentally.
