Abstract We investigate an antiferromagnet/ferromagnet/superconductor/ferromagnet (AF/F/S/F) spin-valve system with nanoscopic scale, described by Usadel equations in the dirty limit. The results show that the superconducting characteristics in the system strongly depend not only on the mutual orientation and thickness of two ferromagnetic layers, but also on the interface transparency and the magnetic scattering. The superconducting critical temperature can exhibit three types of characteristic behaviors with a variation of interface transparency. In particular, the reentrance phenomenon of the superconductivity is observed at the interface transparency γB ξnf =7.1, while the reentrance phenomenon disappears in the presence of magnetic scattering. In addition, it is also found that the introduction of magnetic scattering results in the decrease of the spin-valve effect. The obtained results could provide some practical recommendations for the spin-valve effect in experimental observation.
