Abstract
We theoretically study the vortex states in superconducting multilayer s of Nb/NbTi and Nb/NbZr. We solve the Ginzburg-Landau equations numer ically and find two different vortex lattices as equilibrium vortex ph ases. From the free energy calculations, we determine the phase bounda ry between the vortex phases and map a phase diagram. The magnetizatio n curve exhibits a jump at the phase boundary.
