High Energy Spin Excitations in Electron Overdoped NaFe0.7Ni0.3As
The interplay between magnetism and superconductivity in iron-based high-temperature superconductors are of great interest in condensed matter physics research. These two... -
Incommensurate magnetic fluctuation in KFe2As2 at high energy
We clearly observed incommensurate (IC) magnetic excitation in KFe2As2 above Tc with Ei=80 mev on ARCS at ORNL. Though we got beam time at LET, we wish to see how the IC changes... -

Inelastic neutron study to investigate the crystal electronic field of rare-e...
With the degenerate ground states by the competition between the interacting energies and geometrical properties of the crystal lattice at a specific given site, the... -
Phonon measurements of the incommensurate phase transition in Åkermanite
The proposal is to measure the inelastic scattering from a single crystal of Åkermanite on cooling towards and through the incommensurate phase transition at 358 K. There are... -
Search for spin excitations and spin resonance in ThFeAsN1-xOx (x=0 and 0.3)
Recently, the first nitrogen-containing iron pnictide superconductors ThFeAsN, has been discovered with Tc = 30 K. We have investigated the gap symmetry in ThFeAsN using musr.... -
Relaxation dynamics of a Dy-based single molecule magnet
Single-molecule magnets (SMM) exhibiting slow magnetic relaxation have attracted increasing interest, both from a fundamental point of view, and for the potential practical... -
The Neutron Scattering Spin Resonance: A probe of the momentum structure of t...
We propose to use MERLIN to examine the full magnetic excitation spectrum Chi¿(q,w) of optimally doped Fe based superconductor BaFe1.84Co0.16As2. The primary goal of this... -
Resolving the crystal field scheme for Dy3+ in DyNiAl4
The intermetallic series RNiAl4 (R = rare earth) exhibit interesting low temperature magnetic behaviour including a variety of (in)commensurate magnetic phases and metamagnetic...
