Abstract
In this article, we focus on the dip structure of tunneling spectra in overdoped Bi2Sr2CaCu2O8+δ (Bi2212), measured in Bi2212/vaccum/Bi2212 junctions, which are of the superconductor/insulator/superconductor (SIS) type below Tc. It is confirmed that the dip structure appears at voltages |V| ∼ (2Δ0+Eres)/e in the SIS type tunneling spectra, where 2Δ0 is twice the d-wave superconducting (SC) gap amplitude and Eres the energy of an antiferromagnetic (AF) resonance mode. Furthermore, it is demonstrated that the temperature evolution of the dip structure is in good agreement with that of the AF resonance mode, which also develops below Tc. These results suggest that the tunneling dip structure will be associated with the development of AF resonance mode in accordance with the SC transition.
