We make use of the slave-boson approach to investigate the magnetic properties of the one-dimensional t y J model in Ε½ . 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
