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 Tl₂Ba₂CuO_6+δ, performed near optimum doping ( T_c ∼ 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.
