Emerging superconductivity in nearly anti-ferromagnetic Cuprates

Guy Deutscher

The High Temperature Superconductors discovered by Bednorz and Mueller derive from anti-ferromanetic cuprates by the addition of carriers that destroy the AF state and induce metallicity. Experiments indicating that as more carriers are added the superconducting pairing mechanism may evolve from real pairing to the conventional BCS k-space pairing will be reviewed. A recent proposal that the emergence of superconductivity is preceded by strong lattice disorder (1) is in agreement with recent experimental observations
