Abstract

We present a model for the superconductivity in CuO2 planar systems based on the magnetic frustration mechanism introduced recently by Aharony et al.; our model incorporates explicitly the concentration dependence of the Cu++ spin-spin correlation function. We argue that the transport is via holes in the non-bonding in-plane oxygen orbitals. These two features lead to d-state pairing with, in the BCS approximation, a predicted Tc vs x dependence which agrees well experiments on La2-xSrxCuO4.
