Abstract
The evolution with doping of the magnon energy and damping as well as the incoherent spin excitations in lightly-doped copper-oxide supercon ductors (LDCOS) have been investigated within the extended t-J model. The instability of the 2D-AF ground state for the doping n > n(c) almo st-equal-to 2.7% has been obtained.
