详细
Systematic studies of the proximity effect of superconductor/normal metal, superconductor/antiferromagnet and superconductor/ferromagnet in structures with varying thickness of the superconducting lead layer have been carried out. It has been shown that in these systems the behavior of the superconducting transition temperature Tc with decreasing thickness of the superconducting layer is different. For superconductor/antiferromagnet structures, within the limits of the studied lead layer thicknesses, changes in Tc are insignificant. As the lead layer thickness decreases, the electrical resistance ratio RRR (R300K/R10K) decreases significantly, which may indicate an increase in the contribution of surface defects. The width of superconducting transitions increases with decreasing thickness of the lead layer, which indicates the manifestation of size effects.
