Engineering chiral and topological orbital magnetism of domain walls and skyrmions

摘要: Electrons that are slowly moving through chiral magnetic textures can effectively be described as if they were influenced by electromagnetic fields emerging from the real-space topology. This adiabatic viewpoint has been very successful in predicting physical properties of magnets. Here, based on a rigorous quantum-mechanical approach, we unravel emergence and topological orbital magnetism one- two-dimensional spin systems. We uncover quantized limit understood Landau-Peierls response to emergent field. Our central result is spin–orbit interaction interfacial skyrmions domain walls used tune over orders magnitude merging topology with reciprocal space. findings point out route experimental engineering systems, thereby paving way field orbitronics. Electronic often discussed language fields. The authors theoretically investigate its applicability promises which lie beyond, revealing unique fingerprints magnetism.
