Abstract:
The spin valve effect for the superconducting current based on the
superconductor/ferromagnet proximity effect has been studied for a
CoO$_x$/Fe1/Cu/Fe2/Cu/Pb multilayer. {The magnitude of the effect $\Delta T_c
=T_c^{\text{AP}} -T_c^{\text{P}}$, where $T_c^{\text{P}}$ and
$T_c^{\text{AP}}$ are the
superconducting transition temperatures for the parallel (P) and antiparallel
(AP) orientation of magnetizations, respectively, has been measured for
different thicknesses of the Fe1 layer $d_{\text{Fe1}}$. The obtained dependence
of the effect on $d_{\text{Fe1}}$ reveals that $\Delta T_c$} can be
increased in comparison with the case of a half-infinite Fe1 layer considered by
the previous theory. A maximum of the spin valve effect occurs at
$d_{\text{Fe1}}\sim d_{\text{Fe2}}$. At the optimal value of $d_{\text{Fe1}}$
almost full switching from the normal to the
superconducting state when changing the mutual orientation of magnetizations of
the iron layers Fe1 and Fe2 from P to AP is demonstrated.
