AbstractThe energy scales in rare-earth-based heavy-fermion compounds are relatively small, which can be easily tuned by applying pressure, magnetic field, or chemical doping. By substituting Yb for Ce on the rare-earth site, the ground state of superconductivity can be smoothly suppressed without the appearance of an apparent quantum critical point, and a number of remarkable phenomena have been observed. The slight changes in the electronic structure are supposed to dominate the underlying physics in these compounds. In the present study, we provide an electronic structure study of Ce0.85Yb0.15CoIn5 with a superconducting state but suppressed transition temperature by angle-resolved photoemission spectroscopy, and the results are compared with CeCoIn5. We find that the f electrons in Ce0.85Yb0.15CoIn5 are itinerant, forming the weakly dispersive hybridized band at low temperature. More interestingly, the hybridization strength between the f electrons and conduction electrons in Ce0.85Yb0.15CoIn5 is comparable with CeCoIn5. Further temperature-dependent measurements provide direct evidence of the localized-to-itinerant crossover behavior of the 4f electrons in this compound.
