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...
