  • Abstract
    We have studied the behavior of Hc2 for the Nb1-xTix system as a function of disorder (i.e, x). To account for the observed behavior we substituted expressions for γ and Tc, previously derived for disordered systems, into the GLAG expression for Hc2. This extension accounts very well for the data for the NbTi system and, accordingly, we are studying its application to data for several other superconducting systems.
