Our study investigates the self-spin swapping phenomenon and measures its intensity. Self-spin swapping occurs in a single magnetic layer, where spin current generated, is influenced by surrounding layers. The spin polarization changes and exerts torque to magnetization which is different to that of spin Hall effect. The intensity is affected by not only the neighboring heavy metal layer but also the sample structure. Au layer enhances spin swapping, while Pt layer disrupts spin information. Thus, symmetric structures show weak spin swapping, while asymmetric structures exhibit stronger spin swapping effects.
