CA23136 - Magnetism and chirality: twisting spins, light, and lattices for faster-than-ever spintronics (CHIROMAG)

The ability to switch magnets between two stable states has become the fastest and most widely used means to store information on devices. For information processing however, the standard von Neumann architecture is rapidly becoming obsolete, driven by the modern demands of computational resources for ultrahigh-speed mobile networks, machine learning and artificial intelligence. Recent years have witnessed a strong surge in research on symmetry-driven phenomena in magnetism, concentrated on the effects introduced by chirality. Chiral magnetic states, with their flexibility and topological protection, have great potential to become the building blocks for processing and storage of information. However, the area of chiral magnetism is still in its infancy, with many fundamental challenges to be solved and numerous obstacles to overcome before applications can be realised. The ultimate challenge is to discover ultrafast and energy-efficient ways to control magnetic topological states, the main aim of  CHIROMAG. This will be achieved using an open and inclusive approach that will join the existing expertise and capabilities of scientific communities across Europe dealing with ultrafast magnetism, spintronics, magnonics, photonics and advanced spectroscopy, and by sharing the new knowledge arising from the exchange between them. This Action will result in disruptive achievements in the area of ultrafast chiral magnetism in particular, and in the quality and effectiveness of research in Europe in general, by bridging the existing gaps between these areas. A new generation of scientists will be trained at the interfaces of the involved disciplines, translating scientific breakthroughs into innovative technological solutions.
