Abstract

Topological magnetism has sparked an unprecedented age in quantum technologies. Marked by twisted spin structures with exotic dynamical modes, topological magnets have motivated a new generation of spintronic devices which transcend the limits of conventional semiconductor-based electronics. While existing material probes have biased studies and device conceptualizations for thin samples in two dimensions, advancements in three-dimensional probing techniques using beams of neutrons, are transforming our understanding of topological and emergent physics to reimagine spintronic devices. Here, we review recent neutron scattering breakthroughs which harness quantum degrees of freedom to enable three-dimensional topological investigations of quantum materials. We discuss applications of structured and tomographic neutron scattering techniques to topological magnets, with particular emphasis on magnetic skyrmion systems and their inspired three-dimensional logic device infrastructures through novel multi-bit encoding and control schemes. SANS-based dynamic visualizations and coherent manipulations of three-dimensional topological qubits are proposed using electric field controls of depth-dependant helicities and spin-orbit tuning of the neutron beam. Together, these investigations uncover a new world of three-dimensional topological physics which enhances spintronic devices through a novel set of structures, dynamics, and controls, unique to three-dimensional systems.
