When the isotope exponent goes into the negative, the proton was discovered to be the major player at this stage which determined the experimental values of the critical temperatures of Bi2212, Bi2223, Tl2201, Tl2212, Cu2234, Pb1212, Tl1212, Ru1212, Au1212, Y123, Hg1201, Hg1212 and Tl2223. The mechanism of the high temperature cuprates was proved to be electronic only at this stage. The abnormalities observed in the high temperature cuprates was traced to the strange bond which exist between peculiar elements. Perhaps the bonding of high temperature cuprates is yet to be discovered.application/mswordQC PhysicsArticle
