Interplay between intrinsic magnetism, semiconductivity and   superconductivity in a single CuO_2 plane
  In this paper, an attempt is made to elucidate some aspects of the charge transport in a single CuO_2 plane. During the doping process, the simultaneously introduced oxygen holes as well as the electrons create two components plasma. Whereas the oxygen holes generate a crystal lattice controlled by the repulsive Coulomb force, the conduction electrons having significant momentum components in diagonal directions of the CuO_2 plane are locked in an "electron wave guide" which is the consequence of multiple magnetic scattering on diagonally running chains of Cu atoms with mutually opposite spins, i.e. magnetic stripes. The oxygen holes lattice and the magnetic stripes are confinements for moving conduction electrons and their mutual modulation leads directly to pairs of parallel electron currents, which are equivalent to moving pairs of electrons. This kind of electron currents can exist as long as the antiferromagnetic background exists, i.e. up to the Curie temperature. In turn, the oxygen hole lattice can exist as long as the Coulomb forces balance the longitudinal and the transversal thermal displacements of oxygen hole from their equilibrium positions in the hole lattice.
