3D nano-magnonics and topological spintronics

Extending of nanomagnets into the third dimension is a vibrant research avenue in modern magnetism, including investigations of 3D frustrated systems, curvilinear nanomagnets and the dynamics of spin waves in 3D magnonic systems. In magnon spintronics, concerned with spin waves and their use in information processing systems, spin-wave conduits have traditionally been patterned planar structures. At the same time, extension of magnon circuits into the third dimension is required for the reduction of footprints of magnonic logic gates and allows for steering of spin-wave beams in graded-index magnonics.
