摘要
It is demonstrated that in superconductor-ferromagnet-superconductor (S/F/S) systems in the case of low interface transparency the transition into pi-phase is not related with the oscillations of the superconducting order parameter in F-layer. Consequently, the pi-phase may exist at very thin F-layer thickness. The crossover from pi- to 0-phase results in the nonmonotonous temperature dependence of the critical current.
