Abstract

A systematic study is performed of the superconductor/normal metal, superconductor/antiferromagnet, and superconductor/ferromagnet proximity effects in structures with superconducting lead layers of variable thickness. It is shown that temperature Ts of the superconducting transition in these systems behaves differently when the superconducting layer is thinned. In superconductor/antiferromagnet structures, Ts changes negligibly within the investigated range of lead layer thickness. Ratio RRR (R300 K/R10 K) of electrical resistance falls notably as the lead layer thins, which could indicate a growing contribution from surface defects. The width of superconducting transitions grows as the lead layer thins, testifying to size effects.

超导铅层厚度可变的薄膜异质结构中的邻近效应实验研究
摘要 对厚度可变的超导引线层结构中的超导体/普通金属、超导体/反铁磁体和超导体/铁磁体接近效应进行了系统研究。研究表明,当超导层变薄时,这些系统中超导转变的温度 Ts 表现不同。在超导体/反铁磁体结构中,Ts 的变化在所研究的铅层厚度范围内可以忽略不计。电阻比 RRR(R300 K/R10 K)随着铅层的减薄而明显下降,这可能表明表面缺陷的贡献越来越大。超导跃迁的宽度随着铅层的变薄而增加,这证明了尺寸效应。
