Fermi liquid behaviour in an underdoped high Tc superconductor
Suchitra E. Sebastian, N. Harrison, M. M. Altarawneh +4
We use magnetic quantum oscillations in the underdoped high Tc superconductor YBa_2Cu_3O_(6+x) (x=0.56) measured over a broad range of temperatures 100 mK<T<18 K to extract the for…
Encapsulated Single Crystal Growth and Annealing of the High-Temperature Superconductor Tl-2201
D. C. Peets, Ruixing Liang, Mati Raudsepp +2
Highly-perfect platelet single crystals of Tl_2Ba_2CuO_{6+d} (Tl-2201) were grown by a self-flux technique. A novel encapsulation scheme allowed the precursors to react prior to th…
Possible Microscopic Doping Mechanism in Tl-2201
D. C. Peets, D. G. Hawthorn, Ruixing Liang +2
X-ray absorption spectroscopy on oxygen-annealed, self-flux-grown single crystals of Tl-2201 suggests a microscopic doping mechanism whereby interstitial oxygens are attracted to c…
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…
Nernst and Seebeck Coefficients of the Cuprate SuperconductorYBaCuO: A Study of Fermi Surface Reconstruction
J. Chang, R. Daou, Cyril Proust +13
The Seebeck and Nernst coefficients and of the cuprate superconductor YBaCuO (YBCO) were measured in a single crystal with doping in magnetic fields…
