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.
摘要
在重费米子超导体CeCoIn(5)中以百分比水平掺杂镉，可作为一种电子调谐剂，灵敏地改变超导性和反铁磁性之间的平衡，并为重费米子基态研究开辟新的常压相空间。
