Abstract:
The proximity effect was studied in a thin-film Fe-Cr-V-Cr-Fe layered system. As the chromium layer thickness (d Cr) increases at a fixed thickness of iron layers (d Fe), the dependence of the superconducting transition temperature (T c) on d Cr exhibits a maximum at d Cr ≃ 40 Å followed by a sharp decrease. Investigation of the dependence of T c on d Fe at a fixed d Cr showed that the depth of penetration of the Cooper pairs into a chromium layer does not exceed 40 Å. Analysis of the results obtained suggests that, at d Cr ≃ 40 Å, chromium layers exhibit the transition from a nonmagnetic state to an incommensurate spin density wave state.
