Engineering Chiral and Topological Orbital Magnetism of Domain Walls and Skyrmions

摘要: Electrons which are slowly moving through chiral magnetic textures can effectively be described as if they where 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 that 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.
