Quantum oscillations in antiferromagnetic CaFe2As2 on the brink of superconductivity
N. Harrison, R. D. McDonald, C. H. Mielke +3
We report quantum oscillation measurements on CaFe2As2 under strong magnetic fields- recently reported to become superconducting under pressures of as little as a kilobar. The larg…
Superconductivity and the Effects of Pressure and Structure in Single Crystalline SrNiP
F. Ronning, E. D. Bauer, T. Park +3
Heat capacity, magnetic susceptibility, NMR, and resistivity of SrNi2P2 single crystals are presented, illustrating a purely structural transition at 325 K with no magnetism. Bulk…
Superconductivity in SrNi2As2 Single Crystals
E. D. Bauer, F. Ronning, B. L. Scott +1
The electrical resistivity ρ(T) and heat capacity C(T) on single crystals of SrNi2As2 and EuNi2As2 are reported. While there is no evidence for a structural transition in either co…
Superconductivity at 2.2K in La3Ni4P4O2
T. Klimczuk, T. M. McQueen, A. J. Williams +6
We report the observation of superconductivity in La3Ni4P4O2 at 2.2 K. The layer stacking in this compound results in an asymmetric distribution of charge reservoir layers around t…
Andreev Reflection in Heavy-Fermion Superconductors and Order Parameter Symmetry in CeCoIn_5
W. K. Park, J. L. Sarrao, J. D. Thompson +1
Differential conductance spectra are obtained from nanoscale junctions on the heavy-fermion superconductor CeCoIn along three major crystallographic orientations. Consistency a…
Point-contact Andreev reflection spectroscopy of heavy-fermion-metal/superconductor junctions
W. K. Park, H. Stalzer, J. L. Sarrao +6
Our previous point-contact Andreev reflection studies of the heavy-fermion superconductor CeCoIn using Au tips have shown two clear features: reduced Andreev signal and asymmet…
