Spin triplet pairing in high temperature superconductors

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

Various superconductivity mechanisms show that the electron pair is in spin singlet (S=0) belowTc. In contrast with these, our EPR measurements show that the electron pair is in spin triplet (S=1) rather than the spin singlet. Since an intense zero field absorption was observed in the high temperature superconductors of YBa2Cu3O7−y , and YBa2Cu3O7−y F1, which violated various spin-pairing singlet superconductivity mechanisms.
