Recent polarized neutron scattering experiments on $YBa_2 Cu_3 O_7$ have revealed a sharp spectral peak at the $(\pi,\pi)$ in reciprocal lattice centered around the energy transfer of $41\ meV$. We offer a theoretical explanation of this remarkable experiment in terms of a new collective mode in the particle particle channel of the Hubbard model. This collective mode yields valuable information about the symmetry of the superconducting gap.

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
From Magnons to the Resonance Peak: Spin Dynamics in High-T_C Superconducting Cuprates by Inelastic Neutron Scattering
The spin dynamics of high temperature superconductors measured by inelastic neutron scattering is reviewed. The spin susceptibility evolves a lot with increasing doping from the undoped insulating
The magnetic resonance in high-temperature superconductors: evidence for an extended s-wave pairing symmetry
We have identified several important features in the neutron scattering data of cuprates that are difficult to explain in terms of d-wave and isotropic s-wave order parameters. Alternatively, we show
Neutron Scattering and the Magnetic Response of Superconductors and Related Compounds
This review is intended to provide an introduction to the study of superconductors by magnetic neutron scattering. This experimental technique has been particularly important in the study of

A neutron scattering study reveals that the magnetic fluctuations in an iron arsenide superconductor behave according to the conventional theories of metals, unlike the cuprate superconductors.
