Abstract

For Bi₂Sr₂CaCu₂O_8±δ superconductors electronic Raman scattering from high- and low-energy excitations has been studied in relation to the hole doping level, temperature and energy of the incident photons. For underdoped superconductors we conclude that: short range antiferromagnetic correlations persist with hole doping; the holes bind in local preformed pairs of B_1g symmetry and 600 cm^-1 binding energy; the pair concentration increases with temperature reduction until they gain partial coherence and condense into a collective superconducting state.
