| Popis: | We show that a physical realization of the phase diagram proposed by Minnhagen et al. [Phys. Rev. B 78, 184432 (2008)] for so-called generalized fully frustrated XY model on square lattice can be achieved in arrays of SFS (superconductor-ferromagnet-superconductor) junctions near the transition of the junctions to $\pi$-state. Moreover, the phase diagram with such a topology has to be reproduced twice, on both sides of the $0-\pi$ transition. Comment: 4 pages, 5 figures |
