Abstract

Vortex and non-vortex nucleation states are investigated in the superconducting V-layers isolated by Cr layers(dcr=8nm) for the applied magnetic field parallel to the V/Cr multilayers. In the samples with dv>90nm, the parallel upper critical field Hc2|(T) exhibit the crossover from non-vortex to vortex state with decreasing a temperature. At the crossover point T*, we obtained dvξ(T*)=2.3±0.2. Enhancement of Hc2|(0) was observed in the range of 35nm<dv<65nm.
