We examine various aspects of the normal-state phase of CuO2 planes in the high-T-c superconductors. In particular, within the context of the three band Hubbard model, we study as a function of doping the competition between a charge density wave phase induced by oxygen breathing modes, antiferromagnetic order, and paramagnetism. To account for the strong electronic interactions, we use the finite U slave boson method of Kotliar and Ruckenstein.
