Physical realization of the generalized fully frustrated XY model in an array of SFS junctions
Abstract
We show that a physical realization of the phase diagram proposed by Minnhagen et al. [Phys. Rev. B 78, 184432 (2008), 10.1103/PhysRevB.78.184432] for the so-called generalized fully frustrated XY model on a square lattice can be achieved in arrays of superconductor-ferromagnet-superconductor junctions near the transition of the junctions to the π state. Moreover, the phase diagram with such a topology has to be reproduced twice, on both sides of the 0 -π transition.
