The resonant magnetic mode: a common feature of high-$T_C$ superconductors

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${}_{6+\delta }$, 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.
