The high-energy magnetic excitations in the cuprate superconductors have attracted considerable interest recently. We investigate magnetic excitations over the entire energy range in the heavily underdoped YBCO6.35 superconductor with a Tc=18 K. The spin response below 25 meV energy transfers is broad and has been discussed previously. The magnetic response above 25 meV is very similar to the parent insulators with similar spectral weight and spin-wave velocity. The excitations near the zone boundaries are however, much broader in energy than for the parent insulator. The onset of damping coincides approximately with the gap determined from transport measurements. This indicates that a new decay channel for spin waves becomes available above the pseudo-gap.

Wiebe, NHMFL/FSU Inelastic neutron scattering studies of itinerant spin excitations in URu2Si2 near the hidden order transition

We performed extensive neutron scattering studies on the heavy fermion superconductor URu2Si2. Using the C5 triple axis spectrometer at Chalk River, we studied the spin excitations recently reported [C. R. Wiebe, J. A. Janik et al, Nature Physics] above and below the T0 transition. It has become clear from our previous work that these incommensurate itinerant spin excitations account for the entropy change into the hidden order (HO) state. This severely limits the possible theoretical scenarios on the ground state of the HO phase.
