Spinpolarisierten Strömen in Supraleiter-Ferromagnet und Antiferromagnet-Ferromagnet-Heterostrukturen.
Zusammenfassung der Projektergebnisse
In conclusion, one can say that the project has been very successful. We achieved all our goals and, moreover, opened a new route of research. No difficulties arouse in the execution of announced project schedule. Our group has been pleasantly surprised about the large variety and promising potential applications of the obtained results—especially in the context of superconducting spintronics, a dynamically developing field of research with great perspectives. Here, our publications focusing on the spin currents with and without Josephson charge current should be listed. In addition, our research on the interplay of superconducting and magnetic order parameters sheds light on the mechanism of superconductivity in iron-based pnictides. Also, our investigations performed on these structures bust the research in the field of hybrid mesoscopic structures containing superconducting and magnetic layers allowing construction of highly sensitive and precise measurement instruments potentially based on novel physical features like the found within the project chirality characteristic, which raises hope for, if properly controlled, opening of a new field we may term "chiralitronics" or even "superconducting chiralitronics".
