Local measurement of the superfluid density in the pnictide superconductor Ba(FeCo)As across the superconducting dome
Lan Luan, Thomas M. Lippman, Clifford W. Hicks +6
We measure the penetration depth in Ba(FeCo)As using local techniques that do not average over the sample. The superfluid density $ρ_s(T)\equiv1/λ…
Limits on the Superconducting Order Parameter in NdFeAsOF from Scanning SQUID Microscopy
C. W. Hicks, T. M. Lippman, M. E. Huber +3
Identifying the symmetry of the superconducting order parameter in the recently-discovered ferro-oxypnictide family of superconductors, RFeAsOF, where is a rare e…
Globally Anisotropic High Porosity Silica Aerogels
J. Pollanen, K. Shirer, S. Blinstein +5
We discuss two methods by which high porosity silica aerogels can be engineered to exhibit global anisotropy. First, anisotropy can be introduced with axial strain. In addition, in…
Compressed Silica Aerogels for the Study of Superfluid 3He
J. Pollanen, H. Choi, J. P. Davis +5
We have performed Small Angle X-ray Scattering (SAXS) on uniaxially strained aerogels and measured the strain-induced structural anisotropy. We use a model to connect our SAXS resu…
Magnetoresistance of UPt3
T. M. Lippman, J. P. Davis, H. Choi +2
We have performed measurements of the temperature dependence of the magnetoresistance up to 9 T in bulk single crystals of UPt3 with the magnetic field along the b axis, the easy m…
Anisotropic Aerogels for Studying Superfluid He
J. Pollanen, S. Blinstein, H. Choi +4
It may be possible to stabilize new superfluid phases of He with anisotropic silica aerogels. We discuss two methods that introduce anisotropy in the aerogel on length scales…
