Anomalous He-Gas High-Pressure Studies on Superconducting LaO1-xFxFeAs
W. Bi, H. B. Banks, J. S. Schilling +5
AC susceptibility measurements have been carried out on superconducting LaO1-xFxFeAs for x=0.07 and 0.14 under He-gas pressures to about 0.8 GPa. Not only do the measured values of…
Pressure-induced suppression of ferromagnetism in CePdP
T. A. Elmslie, D. VanGennep, W. Bi +5
The correlated electron material CePdP crystallizes in the ThCrSi structure and orders ferromagnetically at 29 K. Lai et al. [Phys. Rev. B 97, 224406 (2018)] found…
Complex pressure-temperature structural phase diagram of honeycomb iridate CuIrO
G. Fabbris, A. Thorn, W. Bi +8
is among the newest layered honeycomb iridates and a promising candidate to harbor a Kitaev quantum spin liquid state. Here, we investigate the pressure and te…
Synchrotron x-ray spectroscopy studies of valence and magnetic state in europium metal to extreme pressures
W. Bi, N. M. Souza-Neto, D. Haskel +9
In order to probe the changes in the valence state and magnetic properties of Eu metal under extreme pressure, x-ray absorption near-edge spectroscopy, x-ray magnetic circular dich…
Interplay of structure and magnetism in LuFe4Ge2 tuned by hydrostatic pressure
M. O. Ajeesh, P. Materne, R. D. dos Reis +15
LuFeGe crystallizes in the ZrFeSi-type structure, hosting chains of Fe-tetrahedra giving rise to geometric frustration and low-dimensionality. The compound orders a…
Competing spin-orbital singlet states in the 4 honeycomb ruthenate AgLiRuO
T. Takayama, M. Blankenhorn, J. Bertinshaw +25
When spin-orbit-entangled -electrons reside on a honeycomb lattice, rich quantum states are anticipated to emerge, as exemplified by the Kitaev materials. Distinct yet equ…
