Abstract
In Chaps. 3 and 4 we saw how the dynamic susceptibility has come to play a pivotal role in interpreting cuprate spin-lattice relaxation data and rationalizing the sharp contrasts in \(T_1\) behavior among sites in and near the \(CuO_2\) planes. The principal driving force in all of the magnetic phenomenology of the cuprates is clearly the AFM fluctuation peak at or near \({\varvec{Q}} = (\pi ,\pi )\), which occurs in varying degrees of dominance depending in an inverse fashion on the degree of carrier doping. This scenario appears to be a unique property of doped Mott insulators.

This relationship is very nearly exact under the assumption that spin hyperfine processes are predominant. However, it has not yet been determined how important the orbital relaxation rates are for the cuprates (see Sect. 5.6).
