Γ3-type Lattice Instability and the Hidden Order of URu2Si2
Tatsuya Yanagisawa, Shota Mombetsu, Hiroyuki Hidaka +7
We have performed ultrasonic measurements on single-crystalline URu2Si2 with pulsed magnetic fields, in order to check for possible lattice instabilities due to the hybridized stat…
Symmetry and correlations underlying Hidden Order in URu2Si2
Nicholas P. Butch, Michael E. Manley, Jason R. Jeffries +6
We experimentally investigate the symmetry in the Hidden Order (HO) phase of intermetallic URu2Si2 by mapping the lattice and magnetic excitations via inelastic neutron and x-ray s…
Neutron Scattering Study of URuReSi with = 0.10: Driving Order towards Quantum Criticality
T. J. Williams, Z. Yamani, N. P. Butch +3
We report inelastic neutron scattering measurements in the hidden order state of URuReSi with = 0.10. We observe that towards the ferromagnetic quantum critical…
Non-Fermi liquid behavior with and without quantum criticality in Ce(1-x)Yb(x)CoIn(5)
T. Hu, Y. P. Singh, L. Shu +4
One of the greatest challenges to Landau's Fermi liquid theory - the standard theory of metals - is presented by complex materials with strong electronic correlations. In these mat…
High pressure transport studies of the LiFeAs analogues CuFeTe2 and Fe2As
Diego A. Zocco, Duygu Y. Tütün, James J. Hamlin +4
We have synthesized two iron-pnictide/chalcogenide materials, CuFeTe2 and Fe2As, which share crystallographic features with known iron-based superconductors, and carried out high-p…
High-pressure study of non-Fermi liquid and spin-glass-like behavior in CeRhSn
D. A. Zocco, A. Slebarski, M. B. Maple
We present measurements of the temperature dependence of electrical resistivity of CeRhSn up to ~ 27 kbar. At low temperatures, the electrical resistivity varies linearly with temp…
