--- _id: '4200' abstract: - lang: eng text: "We studied the Fulde-Ferrell-Larkin-Ovchinnikov-type state established due to the proximity effect in superconducting\r\nNb/Cu_41Ni_59 bilayers. Using a special wedge-type deposition technique, series of 20–35\r\nsamples could be fabricated by magnetron sputtering during one run. The layer thickness of only a few\r\nnanometers, the composition of the alloy, and the quality of interfaces were controlled by Rutherford backscattering\r\nspectrometry, high-resolution transmission electron microscopy, and Auger spectroscopy. The magnetic\r\nproperties of the ferromagnetic alloy layer were characterized with superconducting quantum interference\r\ndevice magnetometry. These studies yield precise information about the thickness and demonstrate the homogeneity\r\nof the alloy composition and magnetic properties along the sample series. The dependencies of the\r\ncritical temperature on the Nb and Cu41Ni59 layer thickness, T_c(d_S) and T_c(d_F), were investigated for constant\r\nthickness d_F of the magnetic alloy layer and d_S of the superconducting layer, respectively. All types of\r\nnonmonotonic behaviors of T_c versus d_F predicted by the theory could be realized experimentally, from\r\nreentrant superconducting behavior with a broad extinction region to a slight suppression of superconductivity\r\nwith a shallow minimum. Even a double extinction of superconductivity was observed, giving evidence for the\r\nmultiple reentrant behavior predicted by theory. All critical temperature curves were fitted with suitable sets of\r\nparameters. Then, T_c(d_F) diagrams of a hypothetical ferromagnet/superconductor/ferromagnet spin-switch core\r\nstructure were calculated using these parameters. Finally, superconducting spin-switch fabrication issues are\r\ndiscussed in detail in view of the achieved results." article_number: '054517' article_type: original author: - first_name: V.
