Assuming the exchange of antiferromagnetic spin fluctuations as the Cooperpairing mechanism we calculate the doping dependence of the resonance peak seenin inelastic neutron scattering and the magnetic coherence effect. Mostimportantly, we find that the resonance peak in the magnetic susceptibility,${Im}\chi({\bf q},\omega)$, appears {\it only} in the superconducting state,that it scales with $T_c$, and that magnetic coherence is a result of a d-waveorder parameter. We further analyze the structure of ${Im}\chi$ below $T_c$,the position of the peak at $\omega_{res}$ and the consequences forphotoemission, tunneling spectroscopy and the optical conductivity.Comment: 5 pages, 4 figures, added reference
