Abstract
The relationship between the spin excitation spectrum and the symmetry of Cooper pairs in cuprous oxide superconductors is studied. It is found that d-wave superconductivity in the hole system induces an Ising-type anisotropy in the effective coupling between Cu spins. The resulting spin gap structure at zero temperature agrees fairly well with recent neutron experiments.
