A novel non-Fermi-liquid state in the iron-pnictide FeCrAs
W. Wu, A. McCollam, I. Swainson +3
We report transport and thermodynamic properties of stoichiometric single crystals of the hexagonal iron-pnictide FeCrAs. The in-plane resistivity shows an unusual "non-metallic" d…
The high-field Fermi surface of YbRh2Si2
P. M. C. Rourke, A. McCollam, G. Lapertot +3
We present quantum oscillation measurements of YbRh2Si2 at magnetic fields above the Kondo-suppression scale H0 ~ 10 T. Comparison with electronic structure calculations is complic…
Magnetic-Field Dependence of the YbRh2Si2 Fermi Surface
P. M. C. Rourke, A. McCollam, G. Lapertot +3
Magnetic-field-induced changes of the Fermi surface play a central role in theories of the exotic quantum criticality of YbRh2Si2. We have carried out de Haas-van Alphen measuremen…
The Fermi surface and f-valence electron count of UPt3
G. J. McMullan, P. M. C. Rourke, M. R. Norman +6
Combining old and new de Haas-van Alphen (dHvA) and magnetoresistance data, we arrive at a detailed picture of the Fermi surface of the heavy fermion superconductor UPt3. Our work…
Critical end-point and metamagnetic quantum criticality in Sr3Ru2O7
May Chiao, C. Pfleiderer, R. Daou +6
We report a metamagnetic critical point at (B*,T*)=(5.1T,1.1K) for magnetic fields applied perpendicular to the (tetragonal) c-axis of Sr3Ru2O7. First-order behaviour well below T*…
