Point-contact Andreev reflection spectroscopy of heavy-fermion-metal/superconductor junctions (2007)
Park, W. K., Stalzer, H., Sarrao, J. L., Thompson, J. D., Pham, L. D., Fisk, Z., ...
Our previous point-contact Andreev reflection studies of the heavy-fermion superconductor CeCoIn$_5$ using Au tips have shown two clear features: reduced Andreev signal and asymmetric background...
Magnetic structure of Cd-doped CeCoIn5 (2007)
Nicklas, M., Stockert, O., Park, Tuson, Habicht, K., Kiefer, K., Pham, L. D., ...
The heavy fermion superconductor CeCoIn5 is believed to be close to a magnetic instability, but no static magnetic order has been found. Cadmium doping on the In-site shifts the balance between...
Interacting Antiferromagnetic Droplets in Quantum Critical CeCoIn_5 (2007)
Urbano, R. R., Curro, N. J., Thompson, J. D., Pham, L. D., Fisk, Z.
The heavy fermion superconductor CeCoIn_5 can be tuned between superconducting and antiferromagnetic ground states by hole doping with Cd. Nuclear magnetic resonance (NMR) data indicate that these...

Reversible Tuning of the Heavy Fermion Ground State in CeCoIn$_5$ (2006)
Pham, L. D., Park, Tuson, Maquilon, S., Thompson, J. D., Fisk, Z.
Cadmium-doping the heavy-fermion superconductor CeCoIn$_5$ at the percent level acts as an electronic tuning agent, sensitively shifting the balance between superconductivity and antiferromagnetism...
Ytterbium divalency and lattice disorder in near-zero thermal expansion YbGaGe (2006)
Booth, C. H., Christianson, A. D., Lawrence, J. M., Pham, L. D., Lashley, J. C., Drymiotis, F. R.
While near-zero thermal expansion (NZTE) in YbGaGe is sensitive to stoichiometry and defect concentration, the NZTE mechanism remains elusive. We present x-ray absorption spectra that show...
