Universal Heat Conduction in YBa_2Cu_3O_6.9
Louis Taillefer, Benoit Lussier, Robert Gagnon +2
The thermal conductivity of YBa_2Cu_3O_6.9 was measured at low temperatures in untwinned single crystals with concentrations of Zn impurities from 0 to 3% of Cu. A linear term kapp…
Search for Structural Modulations in UPt_3 Using Laue X-ray Diffraction
Brett Ellman, Mark Sutton, Benoit Lussier +3
Using synchrotron radiation-based Laue diffraction methods, we have searched for structural anomalies in a single-crystal whisker of the heavy fermion superconductor UPt_3. Our dat…
On the gap structure of UPt: phases A and B
Louis Taillefer, Brett Ellman, Benoit Lussier +1
We have used thermal conduction and transverse sound attenuation to probe the anisotropy of the gap structure in two superconducting phases of UPt. For the low-temperature phas…
Heat Conduction in the Heavy Fermion Superconductor
May Chiao, Benoit Lussier, Brett Ellman +1
We present preliminary measurements of the thermal conductivity of the heavy fermion superconductor UPdAl for the normal and superconducting states at low temperatures. As…
Influence of a magnetic field on the antiferromagnetic order in UPt_3
B. Lussier, L. Taillefer, W. J. L. Buyers +2
A neutron diffraction experiment was performed to investigate the effect of a magnetic field on the antiferromagnetic order in the heavy fermion superconductor UPt_3. Our results s…
Impurity Scattering and Gap Structure in the Anisotropic Superconductor UPt
Benoit Lussier, Brett Ellman, Louis Taillefer
The thermal conductivity, , of the heavy fermion superconductor UPt was measured down to T/10. The absence of a linear term in the temperature dependence as T$\rightarro…
