已知超导体/铁磁体双层表现出临界温度 Tc 对铁磁层厚度 df 的显着依赖性。我们开发了一种研究 Tc 作为双层参数函数的通用方法。结果表明,准粒子的干涉使得Tc(df)成为非单调函数。结果与实验吻合良好。我们的方法也适用于多层结构。
Superconductor/ferromagnet bilayers are known to exhibit nontrivial dependence of the critical temperature Tc on the thickness df of the ferromagnetic layer. We develop a general method for investigation of Tc as a function of the bilayer parameters. It is shown that interference of quasiparticles makes Tc(df) a nonmonotonic function. The results are in good agreement with experiment. Our method also applies to multilayered structures.
