the three curves. For small $d_{F}$ the structure is in the $0$-state *mode (1a)* regime. The difference between dashed and short dashed lines in this area is due to the fact that the inequalities (\[condSup\]) are not fulfilled for very small $d_{F}.$ The solid and short dashed curves start from the same value since for $d_{F}=0$ the sFS electrode becomes a single spatially homogeneous superconductor. For $d_{s}=2\xi _{s}(T)$ the intrinsic superconductivity in the s layer is weak and is partially suppressed with $d_{F}$ increase (see the inset in Fig.\[Ic\_ds\]). This suppression is accompanied by rapid drop of the critical current. It can be seen that starting from the value $d_{F}\approx 0.4\xi _{F}$ our analytical formulas (\[JatIS1\])-([EqDsmall1]{}) are accurate enough. The larger $d_{s},$ the better agreement between numerical and analytical results due to the better applicability of the GL equations in the s layer. With further $d_{F}$ increase the structure passes through the valley of *mode (1b)* state, located in the vicinity of the $0$ to $\pi $ transition, and comes into the $\pi -$state of the *mode (1a)*. Finally for $d_{F}\gtrsim 1.6\xi _{F}$ there is a transition from *mode (1a)* to *mode (1b),* which is accompanied by damped oscillation of
