| 英文摘要 | The interaction between superconductivity and magnetism in heavy fermion compounds has remained a challenge ever since the discovery of unconventional superconductivity in such systems. The heavy fermion CeTIn5 (T = Co,Rh,Ir) family offers a good platform to study the relationship between superconductivity and magnetism, whose ground state can be easily tuned by chemical doping, making the ambient-pressure experimental techniques like angle-resolved photoemission spectroscopy possible to address this old but engaging question. By Cd doping, the superconducting state of CeCoIn5 can be smoothly tuned to an antiferromagnetic ground state, which can be reversed by applying pressure. Here we present an electronic structure study of CeCo(In0.85Cd0.15)(5) with an antiferromagnetic ground state and the results are compared with CeCoIn5 . We found that the hybridization strength between the f electrons and conduction electrons in CeCoIn5 has been suppressed by Cd doping, but still the Fermi surface includes a significant contribution from the Ce f electrons. Our results find that the electronic tuning effect by Cd doping arises from the change in the hybridization strength between the Ce f electrons and conduction electrons caused by the Cd dopant, and the subtle interplay between itinerancy and localization of the f electrons determines the ground state. |
