Evidence that the upper critical field of Nb3Sn is independent of whether it is cubic or tetragonal
Jian Zhou, Younjung Jo, Zu Hawn Sung +3
Although 2011 marks the 50th anniversary of Nb3Sn as the first high field superconductor, real understanding of its upper critical field behavior μ0Hc2 is incomplete. Here we show…
Lifshitz critical point in the cuprate superconductor YBa2Cu3Oy from high-field Hall effect measurements
David LeBoeuf, Nicolas Doiron-Leyraud, B. Vignolle +14
The Hall coefficient R_H of the cuprate superconductor YBa2Cu3Oy was measured in magnetic fields up to 60 T for a hole concentration p from 0.078 to 0.152, in the underdoped regime…
Zooming on the Quantum Critical Point in Nd-LSCO
Olivier Cyr-Choinière, R. Daou, J. Chang +10
Recent studies of the high-Tc superconductor La_(1.6-x)Nd_(0.4)Sr_(x)CuO_(4) (Nd-LSCO) have found a linear-T in-plane resistivity rho_(ab) and a logarithmic temperature dependence…
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…
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…
Linear-T resistivity and change in Fermi surface at the pseudogap critical point of a high-Tc superconductor
R. Daou, David LeBoeuf, Nicolas Doiron-Leyraud +9
A fundamental question of high-temperature superconductors is the nature of the pseudogap phase which lies between the Mott insulator at zero doping and the Fermi liquid at high do…
Quasi-2D superconductivity and Fermi-liquid behavior in bulk CaC
E. Jobiliong, H. D. Zhou, J. A. Janik +4
The intercalated graphite superconductor CaC6 with Tc ~ 11.5 K has been synthesized and characterized with magnetoresistance measurements. Above the transition, the resistivity fol…
