Title

The Weights of Various Features in the Magnetic Spectra of Cuprates

Abstract

We review briefly the magnetic fluctuation spectra, obtained by neutron scattering, of the high temperature superconductor YBa2Cu3O6.6 (Tc = 62.7 K). The resonance at 34 meV is the most prominent spectral feature in the superconducting state. Even so, its net weight accounts for a mere 1 % of the total squared moment expected for planar Cu2+ ions. For context, we also provide a discussion of the spectral weights associated with the magnetic order and spin waves in two-dimensional S = 1/2 Heisenberg antiferromagnets.
