Abstract

We theoretically study the vortex states in superconducting multilayers of Nb/NbTi and Nb/NbZr. We solve the Ginzburg-Landau equations numerically and find two different vortex lattices as equilibrium vortex phases. From the free energy calculations, we determine the phase boundary between the vortex phases and map a phase diagram. The magnetization curve exhibits a jump at the phase boundary.
