Physical Review B | 2013

Experimental observation of the triplet spin-valve effect in a superconductor-ferromagnet heterostructure

V.I. Zdravkov; J. Kehrle; G. Obermeier; D. Lenk; H.-A. Krug von Nidda; C. Müller; M..Y. Kupriyanov; A. S. Sidorenko; S. Horn; R. Tidecks; L. R. Tagirov

The theory of superconductor-ferromagnet heterostructures with two ferromagnetic layers predicts the generation of a long-range, odd-in-frequency triplet pairing at noncollinear alignment (NCA) of the magnetizations of the F layers. This triplet pairing has been detected in a Nb/Cu

A Spin Valve Core Structure based on the Fulde-Ferrell Larkin-Ovchinnikov Like State: Studies on Bilayers and Trilayers of Superconductors and Ferromagnets

V.I. Zdravkov; J. Kehrle; G. Obermeier; C. Müller; D. Lenk; R. Morari; A. S. Sidorenko; S. Horn; R. Tidecks; L. R. Tagirov

spin-valve-type proximity effect heterostructure, in which a very thin Nb film between the F layers serves as a spacer of nc metal. The resistance of the sample as a function of an external magnetic field shows that for not too high fields, the system is superconducting at a collinear alignment of the Cu
