Walters, Toby G. Perring, Jean-Sébastien Caux, Andrei T. Savici, Genda D. Gu, Chi-Cheng Lee, Wei Ku, and Igor A. ZaliznyakNature Physics 5, p.867-872Theories involving highly energetic spin fluctuations are among the leading contenders for explaining high-temperature superconductivity in the cuprates1. These theories could be tested by inelastic neutron scattering (INS), as a change in the magnetic scattering intensity that marks the entry into the superconducting state provides a precise quantitative measure of the spin-interaction energy involved in the superconductivity2,3,4,5,6,7,8,9,10,11. However, the absolute intensities of spin fluctuations measured in neutron scattering experiments vary widely, and are usually much smaller than expected from fundamental sum rules, resu
