Spin Dynamics in Low Dimension and Low Symmetry Environment

While in a textbook example magnetic ordering is governed by exchange interactions with spin-orbit interaction being just a small correction, in low dimension (surface, interfaces, 2D materials) and in low symmetry specimens spin-orbit interaction shows up in the leading order of the Hamiltonian. As a result, spin and orbital degrees of freedom get intertwined yielding CISS- and orbitronic phenomena, magnetic structure is defined by competing interactions leading to complexity, exotic such as skyrmions and hopfions emerge, topology starts to play a decisive role in physics models, and even the unconventional type of ordering - altermagnetic - emerges.

The 2025 GRC Spin Dynamics in Nanostructures is dedicated to the recent and the most counter-intuitive examples of magnetism and spin dynamics in these systems as well as to applications of this fundamental research in alternative data storage, memory and computing hard-ware based systems, with paradigms that go beyond the von Neumann computing (stochastic computing, reservoir computing, neuromorphic computing, superconducting computing, quantum computing etc).
