Spin dynamics in quasi-one-dimensional strongly correlated zigzag materials

Abstract

Within the t-J model, the spin dynamics of the quasi-one-dimensional strongly correlated zigzag type materials is studied based on the fermion-spin theory. It is shown that the pattern of the neutron scattering peaks depends on both the next-nearest neighbor coupling and doping. The weight of the incommensurate neutron scattering peaks decreases with increasing energy.
