Electron pockets in the Fermi surface of hole-doped high-Tc superconductors
David LeBoeuf, Nicolas Doiron-Leyraud, Julien Levallois +11
High-temperature superconductivity occurs as copper oxides are chemically tuned to have a carrier concentration intermediate between their metallic state at high doping and their i…
Quantum oscillations and the Fermi surface in an underdoped high-Tc superconductor
Nicolas Doiron-Leyraud, Cyril Proust, David LeBoeuf +6
Despite twenty years of research, the phase diagram of high transition- temperature superconductors remains enigmatic. A central issue is the origin of the differences in the physi…
de Haas-van Alphen oscillations in the underdoped cuprate YBaCuO
C. Jaudet, D. Vignolles, A. Audouard +11
The de Haas-van Alphen effect was observed in the underdoped cuprate YBaCuO via a torque technique in pulsed magnetic fields up to 59 T. Above an irreversibility fi…
Disorder, Metal-Insulator crossover and Phase diagram in high-Tc cuprates
F. Rullier-Albenque, H. Alloul, F. Balakirev +1
We have studied the influence of disorder induced by electron irradiation on the normal state resistivities of optimally and underdoped YBa2CuOx single crystals, using pulse…
Shubnikov-de Haas oscillations in YBa_2Cu_4O_8
A. F. Bangura, J. D. Fletcher, A. Carrington +10
We report the observation of Shubnikov-de Haas oscillations in the underdoped cuprate superconductor YBaCuO (Y124). For field aligned along the c-axis, the frequency of…
Total suppression of superconductivity by high magnetic fields in YBa2 Cu3O6.6
F. Rullier-Albenque, H. Alloul, Cyril Proust +3
We have studied in fields up to 60T the variation of the transverse magnetoresistance (MR) of underdoped YBCO6.6 crystals either pure or with Tc reduced down to 3.5K by electron ir…
