Dual Features of Magnetic Susceptibility in Superconducting Cuprates: a comparison to inelastic neutron scattering

Abstract

Starting from the generalized t-J-G model Hamiltonian, we analyze the spin response in the superconducting cuprates taking into account both local and itinerant spin components which are coupled to each other self-consistently. Derived expression reproduces the basic observations of neutron scattering data in YBa2Cu3O6+y compounds near the optimal doping level.
