Reversible Tuning of the Heavy Fermion Ground State in CeCoIn$_5$
arXiv:cond-mat/0611655 · doi:10.1103/PhysRevLett.97.056404
Abstract
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 and opening new ambient-pressure phase space in the study of heavy-fermion ground states.
