## Measurements of the critical current J, have been made for the Nb/Nb,&,, multilayer which showed a sharp upturn behavior in a parallel upper critical field W,,,,(T), caused by the shift of the order-parameter A(r) from Nb-to NbZr-layers. In the region where A(r) is localized in the Nb-layers,
Shiba-Rusinov superconductors are superconducting alloys with dilute concentrations of magnetic impurities. They develop localized states inside the energy gap. A full strong coupling theory of the upper critical field (Be2) is presented and numerical results for three different niobium alloys are d
