Of particular interest are magnetic non-volatile memories formed from synthetic antiferromagnetic racetrack nanowires in which chiral composite domain walls ; that act as data bits ; can be efficiently moved by current pulses. However ; overcoming the trade-off between energy efficiency ; namely a low threshold current density and high thermal stability ; remains a major challenge for developing integrated chips with high reliability and low power consumption. In this thesis ; we demonstrate that chiral domain walls in a synthetic antiferromagnet - ferromagnet lateral junction ; formed by local plasma oxidation ; are highly stable against large magnetic fields ; whilst the domain walls can be efficiently moved across the junction by current. ; MagnetismFerromagnets ; Magnetic Domain Walls ; Magnetic Devices ; Spintronics ; Racetrack ; Memory ; Synthetic antiferromagnets ; Ferromagnets ; [...] Origination: University thesis: Dissertation, Halle (Saale), Martin-Luther-Universität Halle-Wittenberg, 2024 Footnote: Access State: Open Access
