AbstractThe properties of the charge imbalance and magnetism are investigated in the multilayered cuprates. The effective Hubbard constants are much reduced and show clear electron-hole asymmetry due to the screening effect. Phase diagrams are obtained, which may give the clue to search for the self-doped cuprates. An unexpected increase of the charge density upon doping in the layer with minority charge is predicted. The antiferromagnetism follows a two-step evolution with respective origin in the layer with minority charge, in contrast to the conventional doping dependence in the layer with major charge.
