想象一张纸，8公里长，700米宽，0.1毫米厚。现在将其缩小到105- 80 mm乘以7 mm，相应地其厚度为10 nm，并且您对在实验中创建薄膜所需的精度和控制有了一个想法，例如Jan-Michael Kehrle及其同事最近在Annalen der Physik上发表的实验[1]。在相对大的面积上产生这种非常薄的薄膜的动机是预测，如果常规超导体的薄层被夹在两个铁磁膜之间，那么这种三层结构的超导转变温度在最初被抑制之后，当一个或两个铁磁层的厚度变化时，将显示出再进入行为。超导临界温度的这种重入行为的机制最终可以追溯到Fulde-Ferrell-Larkin-Ovchinnikov（FFLO）效应。当时在马里兰州大学工作的Peter Fulde和Richard Ferrell于1964年8月在Physical Review B上发表了他们的文章（参考文献3）。在莫斯科物理技术研究所工作的阿纳托利·拉金和尤里·奥夫钦尼科夫于1964年9月在《科学与技术杂志》上发表了一篇关于类似效应的文章（1965年3月在苏联物理学JETP上翻译）（参考文献4 [1]）。
Imagine a piece of paper, 8 km long, 700 m wide, and 0.1 mm thick. Now scale that down by a factor of 105–to 80 mm times 7 mm, and correspondingly its thickness to 10 nm, and you have an idea about the precision and control necessary to create thin films in experiments like the one published recently in Annalen der Physik by Jan-Michael Kehrle and co-workers [1]. The motivation for creating such extraordinarily thin films over comparatively large areas was a prediction that if a thin layer of a conventional superconductor is sandwiched between two ferromagnetic films, then the superconducting transition temperature of this trilayer structure, after initially being suppressed, would show a reentrance behaviour when the thickness of one or both of the ferromagnetic layers is varied. The mechanism for such a reentrant behaviour of the superconducting critical temperature can ultimately be traced back to the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) effect. Peter Fulde and Richard Ferrell, working at the time at the University of Maryland, published their article in August 1964 in Physical Review B (Ref. 3 in [1]). Independently, working at the Moscow Physico-Technical Institute, Anatoly Larkin and Yuri Ovchinnikov published in September 1964 an article about similar effects in Zhurnal Eksperimental’noi i Teoricheskoi Fiziki (which appeared translated in March 1965 in Soviet Physics JETP)(Ref. 4 in [1]).
