By using a Kronig-Penney model, we examined in this paper the extended states of a noninteracting electron in one-dimensional n-mers randomly placed in a crystal. We found at the most in each band of the energy spectrum n -1 resonances corresponding to extended states of the n-mers. Such resonances
We make use of the slave-boson approach to investigate the magnetic properties of the one-dimensional t y J model in ลฝ . 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
