【 摘 要 】

We investigated the critical temperature Tcof SF1F2 trilayers (S is a singlet superconductor, F1 and F2 are ferromagnetic metals), where the long-range triplet superconducting pairing is generated at canted magnetizations of the F layers. We examined the spin-singlet and spin-triplet pairing distributions and their amplitudes as a function of the layers thicknesses under different values of the angle a in the SF1F2 structure to clarify which one of the pairing distributions and how may affect the superconducting Tc.
