Abstract
The magnetic properties of the copper oxide planes in hight
Tc superconductors are represented by a planar 2-d antiferromagnet on a square lattice. We model the magnetic effect of the
addition of holes through doping by the replacement of antiferromagnetic with ferromagnetic plaquettes thereby facilitating
the creation of vortices/antivortices. These magnetic arrangements lead to pair formation of the holes (Cooper pairs) at low
temperatures. We explore some of the consequences of these results for high
Tc superconductors.
