Influence of Interface Exchange Coupling in Multilayered Spintronic Structures

The investigation of the influence of interface exchange coupling on multilayered structures reveals critical insight into the performance and reliability of spintronic devices. This study focuses on how the exchange coupling, mediated by non-magnetic layers, affects the magnetic interaction between adjacent ferromagnetic layers, impacting their overall magnetic stability and domain wall motion. This is particularly relevant in the context of spin-transfer torque phenomena, where the efficiency of spin current-induced switching is paramount. Our research highlights the potential for optimizing the exchange coupling to enhance the performance of multilayered spintronic devices. This can lead to improvements in data retention and write/read speeds of memory devices, which is critical as device dimensions continue to shrink in the nanoscale regime.
