Aksay %J Physics %D 1997 %I arXiv %R 10.1016/S0921-4534(97)00222-0 %X We report inelastic neutron scattering experiments on the doping dependence of the energy and spectral weight of the sharp magnetic resonance peak in YBa_2 Cu_3 O_{6+x}. These measurements also shed light on the relationship between the magnetic excitations in the normal and superconducting states. %U http://arxiv.org/abs/cond-mat/9705103v2
