Study of spin-orbit interactions and interlayer ferromagnetic coupling in Co/Pt/Co trilayers in a wide range of heavy-metal thickness

The spin-orbit torque, a torque induced by a charge current flowing through the heavy-metal-conducting layer with strong spin-orbit interactions, provides an efficient way to control the magnetization direction in heavy-metal/ferromagnet nanostructures, required for applications in the emergent magn...
