A new mechanism for the high‐ T c superconductivity is suggested. The antiferromagnetic order of the Cu spins between two neighbour O holes, i.e. the localized antiferromagnetic correlation may be the origin giving rise to the hole pair. The maximum of T c is calculated for the YBaCuO superconductor using the similar method of calculating the antiferromagnet Neel temperature. The conclusion is made that the maximum of T c for the YBaCuO superconductor is between 107.9 and 155.2 K, and the energy gap 2Δ(0) = 3.54 k B T c .
