Depth-resolved magnetism in ferromagnet/heavy-metal thin films: influence of atomic diffusion on spin-mixing conductance

Abstract: This project aims to investigate the diffusion of tantalum in an amorphous magnetic layer, and the influence of this diffusion on magnetism both through the thickness of the magnetic layer and at the interface with heavy-metals platinum, iridium, tungsten, and tantalum. These structures are typical of those we are using to investigate the spin-Hall effect, a mechanism which can provide highly efficient manipulation of local magnetism required for future magnetic data storage and digital logic applications. To study the spin-Hall effect we are using a magnetoresistance technique which allows us to determine the details of how pure spin-currents, a flow of angular momentum without net charge current flow, crosses the interface from heavy metal to amorphous magnet. This neutron data will enable understanding of interface magnetism, which is intimately linked to spin-Hall magnetoresistance.
