Upper critical field and isotope effect in the oxide superconductors
Description
In a model for which the pairing is due mainly to an electronic mechanism supplemented by a small phonon contribution, the authors study the isotope effect exhibited by the upper critical magnetic field Hc2 and compare with the critical temperature. When paramagnetic impurities are added, very different behaviors are found from that predicted in a pure phonon model. The alignment of the paramagnetic spin by the external magnetic field as well as Pauli limiting is neglected in the calculations
