Patterning Spin-Wave reconfIgurable Nanodevices for loGics and computing.

The global need for ever-increasing computational power has driven the development and downscaling of CMOS technology close to its physical limits, so that the search for novel concepts beyond conventional CMOS electronics has become crucial. The control of spin-waves (also called magnons) in magnetic materials offers a great potential in this view. Spin-waves are propagating perturbations in the alignment of spins in ferromagnetic materials. From the technological point of view, spin-waves hold great promise because they have the potential to merge in one single platform the advantages of electromagnetic waves (typically exploited in photonics), with the versatility and nanoscale dimensions of electronics. Recently, we demonstrated a new technique called thermally assisted magnetic scanning probe lithography (tam-SPL), to realize magnonic building blocks for controlling spin-waves. The main objective of project SWING is to enable major advances in the field of magnonics, by using tam-SPL for stabilizing nanoscale structures in the spin-texture of ferromagnets (such as magnetic domain walls or magnetic vortices), and to use these structures for generating and manipulating spin-waves with unprecedented precision and capabilities. The research objectives of SWING project have been fully reached. We started from the optimization of the t-SPL technique, to the extension of its applicability to new materials and systems, such as synthetic antiferromagnets, out-of-plane magnetized materials, 2D semiconductors. We then moved towards the demonstration of novel spin-wave circuits for confining and steering spin-waves, the stabilization of topological spin textures, up to the final demonstration of a novel optically inspired platform for analog computing. Overall, SWING project had a remarkably high impact on the scientific community, and in particular in the communities of magnetism and nanolithography. Its ground-breaking results pave the way towards a range of applications especially for beyond-CMOS computing, with clear potential for both further scientific investigation and commercial application.
