We make use of the slave-boson approach to investigate the magnetic properties of the one-dimensional t y J model in Ž . the weak-coupling limit Jt 1 y n , where n is the number of electrons per unit cell. In the mean-field approximation at zero temperature we find that the helix spin-density-wave p
We examined the one-dimensional t -J -J' model by numerical diagonalization. This model describes electrons with infinite on-site repulsion, nearest-neighbor transfer t, exchange interaction J and, further, next-nearest-neighbor exchange interaction J'. In the case of one hole and J'/ J;(:0.5, the n
