Single ion scattering contributions to the thermal conductivity of LiHoF_4 and LiY_{96%}Ho_{4%}F_4
James Nikkel, Brett Ellman
We have performed extensive zero-field thermal conductivity measurements on single crystal samples of \LiHoF and \LiYHoF below . By comparing these data to a single ion scat…
Intrinsic Pinning in the High Field C-Phase of UPt_3
Brett Ellman, Louis Taillefer
We report on the a.c. magnetic response of superconducting UPt_3 in a d.c. magnetic field. At low fields (H < H^*), the in-phase susceptibility shows a sharp drop at followed…
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…
Transverse Sound Revisited: A Directional Probe of the A-Phase of
Brett Ellman, Louis Taillefer, Mario Poirier
We have measured the transverse ultrasonic attenuation, , in a well-characterized single crystal of for propagation direction, , in the basal plane and pol…
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…
