Abstract

Inelastic neutron scattering experiments in high- $T_{c}$ cuprates have evidenced a new magnetic excitation present in the superconducting state. In particular, recent experiments on single layer Tl $_{2}$ Ba $_{2}$ CuO $_{6 + I^´}$ , performed near optimum doping ( $T_{c} \sim 90$ K), provide evidence of a sharp magnetic resonant mode below $T_{c}$ , 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.
