Doping-Driven Collapse of the SDW Correlation Gap in SmFeAsOF
Scott C. Riggs, R. D. McDonald, J. B. Kemper +8
We report the Hall resistivity, of polycrystalline SmFeAsOF for four different fluorine concentrations from the onset of superconductivity through the collap…
Exchange parameters of copper-based quasi-two-dimensional Heisenberg magnets measured using high magnetic fields and muon-spin rotation
P. A. Goddard, J. Singleton, P. Sengupta +9
Pulsed-field magnetization experiments (fields of up to 85 T and temperatures down to 0.4 K) are reported on nine organic Cu-based two-dimensional (2D) Heisenberg magnets.…
A mechanism for Fermi-surface-topology tuned superconductivity in the cuprates
Neil Harrison, Ross D. McDonald, John Singleton
Based on recent magnetic-quantum-oscillation, ARPES, neutron-scattering and other data, we propose that superconductivity in the cuprates occurs via a convenient matching of the sp…
Absence of field-induced charge-density wave states in (Per)Pt(mnt)
R. D. McDonald, N. Harrison, P. Goddard +2
Graf {\it et al.} [Phys. Rev. Lett. {\bf 93} 076406 (2004)] recently attributed features in the magnetic-field-dependent longitudinal resistance of (Per)Pt(mnt) to a cascad…
Cyclotron resonance harmonics in the organic superconductor -(BEDT-TTF)SFCHCFSO; observation of a new kind of effective mass renormalization
R. S. Edwards, J. A. Symington, A. Ardavan +5
Cyclotron resonance, along with its second and third harmonics, has been observed in the quasi-two-dimensional organic superconductor -(BEDT-TTF)SFCHC…
