  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.
