Upper critical fields and thermally-activated transport of Nd(O_0.7F_0.3)FeAs single crystal
J. Jaroszynski, F. Hunte, L. Balicas +9
We present measurements of the resistivity and the upper critical field H_c2 of Nd(O_0.7F_0.3)FeAs single crystals in strong DC and pulsed magnetic fields up to 45 T and 60 T, resp…
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…
Log-T divergence and Insulator-to-Metal Crossover in the normal state resistivity of fluorine doped SmFeAsO1-xFx
S. C. Riggs, J. B. Kemper, Y. Jo +8
We report the resistivity of a series of fluorine-doped SmFeAsO1-xFx polycrystalline superconductors in magnetic fields up to 60T. For underdoped samples (x < 0.15), the low temper…
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…
Quantum Oscillations in the Underdoped Cuprate YBa2Cu4O8
E. A. Yelland, J. Singleton, C. H. Mielke +4
We report the observation of quantum oscillations in the underdoped cuprate superconductor YBa2Cu4O8 using a tunnel-diode oscillator technique in pulsed magnetic fields up to 85T.…
The Origin of Weak Ferromagnetism in CaB6
M. C. Bennett, J. van Lierop, E. M. Berkeley +8
We have combined the results of magnetization and Hall effect measurements to conclude that the ferromagnetic moments of lightly doped CaB6 samples display no systematic variation…
