Abstract
Assuming the exchange of antiferromagnetic spin fluctuations as the Cooper pairing mechanism we calculate the doping dependence of the resonance peak seen in inelastic neutron scattering and the magnetic coherence effect. Mos t importantly, we find that the resonance peak in the magnetic susceptibili ty, Im chi (q,omega), appears only in the superconducting state, that it sc ales with T-c, and that magnetic coherence is a result of a d-wave order pa rameter. We further analyze the structure of Im chi below T-c, the position of the peak at omega (res) and the consequences for photoemission, tunneli ng spectroscopy, and the optical conductivity.
