摘要

Eminent inelastic neutron scattering (INS) measurements of high temperature cuprates currently lacking theoretical interpretations are the observed temperature dependence of magnetic resonance peak and linear scaling relation between the resonance peak energy, E-res and the superconducting transition temperature, T-c. Using our slave-boson approach of the t-J Hamiltonian (Phys. Rev. 64, 052501 (2001)) for this study, we show that starting from the pseudogap temperature T*, the magnetic resonance peak increases with decreasing temperature, revealing its inflection point at Tc and that spin pairing correlations are responsible for d-wave superconductivity. We find that there exists a universal linear scaling behavior of E-res/T-c = const., irrespective of the Heisenberg exchange coupling.
