A multi-component Fermi surface in the vortex state of an underdoped high-Tc superconductor
Suchitra E. Sebastian, N. Harrison, E. Palm +6
In order to understand the origin of superconductivity, it is crucial to ascertain the nature and origin of the primary carriers available to participate in pairing. Recent quantum…
A cascade of magnetic field induced spin transitions in LaCoO3
M. M. Altarawneh, G. -W. Chern, N. Harrison +9
We present magnetization and magnetostriction studies of the insulating perovskite LaCoO3 in magnetic fields approaching 100 T. In marked contrast with expectations from single-ion…
Compensated electron and hole pockets in an underdoped high Tc superconductor
Suchitra E. Sebastian, N. Harrison, P. A. Goddard +7
We report quantum oscillations in the underdoped high Tc YBCO over a wide range in magnetic field 28<B<85 T corresponding to ~12 oscillations, enabling the Fermi surface topology t…
Metal-insulator quantum critical point beneath the high Tc superconducting dome
Suchitra E. Sebastian, N. Harrison, M. M. Altarawneh +5
An enduring question in correlated systems concerns whether superconductivity is favoured at a quantum critical point (QCP) characterised by a divergent quasiparticle effective mas…
Spin-order driven Fermi surface revealed by quantum oscillations in an underdoped high Tc superconductor
Suchitra E. Sebastian, N. Harrison, C. H. Mielke +4
We use quantum oscillation measurements to distinguish between spin and orbital components of the lowest energy quasiparticle excitations in YBa2Cu3O6.54, each of which couple diff…
2D XY Behavior observed in quasi-2D quantum Heisenberg antiferromagnets
F. Xiao, F. M. Woodward, C. P. Landee +8
The magnetic properties of a new family of molecular-based quasi-two dimension Heisenberg antiferromagnets are reported. Three compounds, (, $Cu(pz)_2(BF…
Comparison of the Fermi-surface topologies of kappa-(BEDT-TTF)_2 Cu(NCS)_2 and its deuterated analogue
R. S. Edwards, A. Narduzzo, J. Singleton +2
We have measured details of the quasi one-dimensional Fermi-surface sections in the organic superconductor kappa-(BEDT-TTF)_2 Cu(NCS)_2 and its deuterated analogue using angle-depe…
A statistical model for the intrinsically broad superconducting to normal transition in quasi-two-dimensional crystalline organic metals
J. Singleton, N. Harrison, C. H. Mielke +2
Although quasi-two-dimensional organic superconductors such as -(BEDT-TTF)Cu(NCS) seem to be very clean systems, with apparent quasiparticle mean-free paths of several t…
Thermal activation between Landau levels in the organic superconductor -(BEDT-TTF)SFCHCFSO
M. -S. Nam, A. Ardavan, J. A. Symington +6
We show that Shubnikov-de Haas oscillations in the interlayer resistivity of the organic superconductor -(BEDT-TTF)SF CHCFSO become very pronounc…
