Fig. 3: Spin transport in multilayered structures.

Schematic illustration of spin-dependent electron transport in a ferromagnetic (F) and non-magnetic (NM) multilayered structure under parallel and antiparallel configurations. In the parallel configuration (left), the magnetizations of the F layers are aligned, allowing spin-polarized electrons to travel with minimal scattering, resulting in lower resistance. In the antiparallel configuration (right), alternating magnetization directions cause increased spin scattering, leading to higher resistance.
