Key features for high-Tc-superconductivity phenomenon: antiferromagnetic exchange as attractrive interaction and a saddle-point singularity close to Fermi level

摘要

A new mechanism for high-Tc superconductivity of magnetic origin is pro-jjpsat, different from exchange by spin-waves. A superconducting pairing of fir d-umvc symmetry with high amplitude of the SC gap is found
