Physical Review Letters, 87(6), 67005-1-670054. doi:10.1103/PhysRevLett.87.0670050031-90071079-7114https://doi.org/10.1103/PhysRevLett.87.067005https://hdl.handle.net/11147/7137New break-junction tunneling data are reported in Bi2Sr2CaCu2O8+δ over a wide range of hole concentration from underdoped (Tc=74k) to optimal doped (Tc=95k) to overdoped (Tc=48k). The conductances exhibit sharp dips at a voltage, Ω/e, measured with respect to the superconducting gap. Clear trends are found such that the dip strength is maximum at optimal doping and that Ω scales as 4.9kTc over the entire doping range. These features link the dip to the resonance spin excitation and suggest quasiparticle interactions with this mode are important for superconductivity.eninfo:eu-repo/semantics/openAccessScanning tunneling spectroscopyResonance spin excitationPhonon mechanismArticle2-s2.0-7995745614110.1103/PhysRevLett.87.067005
