The t-U-V-J model is used to describe the positions of the experimental peaks associated with commensurate and incommensurate structure of the magnetic susceptibility probed by neutron scattering in cuprate compounds. Assuming that the tight-binding form of the mean-field electron energy and the maximum gap can be obtained by fitting the angle-resolved photoemission spectroscopy (ARPES) data, we have determined the strengths of the on-site repulsive interaction U, the spin-independent attractive interaction V and the spin-dependent antiferromagnetic interaction J from the positions of the commensurate and incommensurate peaks.
