英文摘要	Tunneling spectra of Bi2Sr2CaCu2O8+delta intrinsic Josephson junctions with different doping are analyzed and reproduced using a d-wave Eliashberg formalism in a wide temperature range below T-c from which the pairing glue spectral function alpha F-2(Omega) composed of a low-energy resonance peak and a high-energy broad spectrum is obtained. As temperature increases toward T-c, the resonance peak shows continuous decrease both in energy and in height while the broad spectrum slightly increases in height. The calculated coupling constant demonstrates an important role for pairing by the broad spectrum that originates from spin fluctuations. The gap function extracted from the analysis bears a close resemblance to the recent Hubbard and t-J model simulations. We discuss the limitations of the d-wave Eliashberg approach used in our analysis. (C) 2015 Elsevier B.V. All rights reserved.
