Inelastic neutron scattering experiments in high-Tc cuprates have evidenced a new magnetic excitation present in the superconducting state. In particular, recent experiments on single layer Tl₂Ba₂CuO₆₊δ, performed near optimum doping (Tc 90 K), provide evidence of a sharp magnetic resonant mode below Tc, similar to previous reports on the YBCO and BSCCO bilayer systems. This result supports models that ascribe a key role to magnetic excitations in the mechanism of superconductivity.
