Lorentzian form for the imaginary part of the dynamic spin susceptibility: comparison with NQR and Neutron Scattering data in copper oxide superconductors
Abstract
We present some new results based on the relaxation function theory for a doped two-dimensional Heisenberg antiferromagnetic system with damping of paramagnon-like excitations. The Lorentzian form for the imaginary part of the dynamic spin susceptibility gives a reasonable agreement with neutron scattering and plane copper nuclear spin-lattice relaxation rate 63(1/T1) data in right up to optimally doped La2-xSrxCuO4.
