The anisotropy of the spin fluctuations in the electron nematic phase of Sr3R...
New electronic phases often emerge in the proximity of a quantum critical point (QCP) - that is the point where the transition temperature of a collective phase transition is... -
Uniaxial pressure effect in FeTe
Superconductivity in iron-based materials occurs in close proximity to a long-range ordered magnetic phase. In the iron pnictides, uniaxial pressure shifts the magnetic ordering... -
Neutron diffraction and inelastic neutron scattering study on NdT2Al10 (T= Ru...
We have investigated the magnetic structure and crystal field excitations (CEF) of CeT2Al10 (T=Os and Ru). The observed magnetic moment along the c-axis does not agree with that... -
The study of spin excitations in superconducting LiFeAs
The spin excitations in superconducting LiFeAs have been found evolved from incommensurate peaks to commensurate peak at low energy. But the spin resonance is still not clear in... -
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... -

Recentely we have measured (RB 1620263) pressure dependence of phonon modes in both the protonated (H2O) and deuterated ice (D2O) (Fig. 2) at ambient, 0.3 kbar, 1.0 kbar and 1.6... -
Two Kondo scales and crystal-field excitations in CeRuSn
At room temperature the ternary stannide CeRuSn crystallizes with a super structure of the monoclinic CeCoAl-type structure. Charge ordering produces a doubling of the unit cell... -
