Heat Conduction in the Vortex State of NbSe_2: Evidence for Multi-Band Superconductivity
Etienne Boaknin, M. A. Tanatar, Johnpierre Paglione +8
The thermal conductivity kappa of the layered s-wave superconductor NbSe_2 was measured down to T_c/100 throughout the vortex state. With increasing field, we identify two regimes:…
Local Magnetic Susceptibility of the Positive Muon in the Quasi 1D S=1/2 Antiferromagnet KCuF
J. Chakhalian, R. F. Kiefl, R. Miller +7
We report muon spin rotation measurements of the local magnetic susceptibility around a positive muon in the paramagnetic state of the quasi one-dimensional spin 1/2 antiferromagne…
Magnetic flux jumps in textured Bi2Sr2CaCu2O(8+d)
A. Nabialek, M. Niewczas, H. Dabkowska +3
Magnetic flux jumps in textured Bi2Sr2CaCu2O(8+d) have been studied by means of magnetization measurements in the temperature range between 1.95 K and Tc, in an external magnetic f…
Top-Seeded Melt-Growth of YBa_2Cu_3O_x Crystals for Neutron Diffraction Studies
D. C. Peets, Ruixing Liang, C. Stock +6
We have grown cubic centimetre-size crystals of YBa2Cu3Ox suitable for neutron studies, by a top-seeded melt-growth technique. Growth conditions were optimized with an eye toward m…
Understanding Paramagnetic Spin Correlations in the Spin-Liquid Pyrochlore Tb2Ti2O7
Ying-Jer Kao, Matthew Enjalran, Adrian Del Maestro +2
Recent elastic and inelastic neutron scattering studies of the highly frustrated pyrochlore antiferromagnet Tb2Ti2O7 have shown some very intriguing features that cannot be modeled…
muSR linewidth and isotropic pairing in superconducting PrOs4Sb12
D. E. MacLaughlin, J. E. Sonier, R. H. Heffner +7
Transverse-field muon spin rotation measurements in the vortex-lattice mixed state of the heavy-fermion (HF) superconductor PrOs4Sb12 yield a temperature dependence of the penetrat…
Antiferromagnetic fluctuations and d-wave superconductivity in electron-doped high-temperature superconductors
B. Kyung, J. S. Landry, A. -M. S. Tremblay
We show that, at weak to intermediate coupling, antiferromagnetic fluctuations enhance d-wave pairing correlations until, as one moves closer to half-filling, the antiferromagnetic…
Hexatic-Herringbone Coupling at the Hexatic Transition in Smectic Liquid Crystals: 4- Renormalization Group Calculations Revisited
Mohammad Kohandel, Michel J. P. Gingras, Josh P. Kemp
Simple symmetry considerations would suggest that the transition from the smectic-A phase to the long-range bond orientationally ordered hexatic smectic-B phase should belong to th…
Neutron scattering search for static magnetism in oxygen ordered YBa2Cu3O6.5
C. Stock, W. J. L. Buyers, Z. Tun +5
We present elastic and inelastic neutron scattering results on highly oxygen ordered YBa2Cu3O6.5 ortho-II. We find no evidence for the presence of ordered magnetic moments to a sen…
The Structural Evolution of Substructure
Eric Hayashi, Julio F. Navarro, James E. Taylor +2
We investigate the evolution of substructure in cold dark matter halos using N-body simulations of tidal stripping of substructure halos (subhalos) within a static host potential.…
Heat Transport in a Strongly Overdoped Cuprate: Fermi Liquid and Pure d-wave BCS Superconductor
Cyril Proust, Etienne Boaknin, R. W. Hill +2
The transport of heat and charge in the overdoped cuprate superconductor Tl_2Ba_2CuO_(6+delta) was measured down to low temperature. In the normal state, obtained by applying a mag…
Structural Ordering and Symmetry Breaking in Cd_2Re_2O_7
J. P. Castellan, B. D. Gaulin, J. van Duijn +6
Single crystal X-ray diffraction measurements have been carried out on Cd_2Re_2O_7 near and below the phase transition it exhibits at Tc' ~195 K. Cd_2Re_2O_7 was recently discovere…
Spin Ice State in Frustrated Magnetic Pyrochlore Materials
Steven T. Bramwell, Michel J. -P. Gingras
A frustrated system is one whose symmetry precludes the possibility that every pairwise interaction (``bond'') in the system can be satisfied at the same time. Such systems are com…
