Spin Dynamics and Manipulation Near and Far From Equilibrium in New Materials, Scales and Geometries

The rapid evolution of the fields of spintronics, nanomagnetism, and magnonics is constantly fueled by the technological necessity of our era, demanding faster and more efficient alternatives to computing that can satisfy our ever-increasing societal demands. This has led to the discovery of new materials and novel computational concepts geared towards artificial intelligence (AI), where a circular revolution is seeing a return to analog from digital, where flexible and multifunctional materials and the devices will do directly the computation in a non-digital form and at broad time scales. In the materials front, antiferromagnetic and topological magnetic materials, both metallic and insulating, are leading the discoveries at a neck breaking pace – they are functional in both near and far from equilibrium and under extreme regimes of time scales and lengths – showing the potential to bridge the THz communication gap.

In the front of new phases and regimes, the realization of magnetism in two-dimensional materials, continues to challenge our prior understanding of magnetism at the verge. These two-dimensional systems have many topological regimes that are now beginning to be explored, connecting strain – through phonons – directly with their electrical and optical properties. This has also created a bridge to magnetic topological systems, where magnetism, topological quasiparticles that affect dramatically Hall transport and spin-current generation, have come together to bring new paradigms in magnetic order manipulation.

Finally, as already mentioned above, alternative computing hard-ware based systems, with paradigms that go beyond the von Neumann computing, are rapidly emerging – with stochastic computing, reservoir computing with Skyrmions, and neuromorphic computing with ferromagnetic-antiferromagnetic systems, among the few recent examples. This GRC will provide an open platform for new questions and challenges in these highly active and emerging areas of spintronics, nanomagnetism, and magnonics. As in the successful previous conference, each session will begin by a tutorial/overview of the state-of-the-art and most recent development, focusing in particular on the open challenges in the field, followed by talks on each field on the latest developments in that area.
