Three-Dimensional Neutron Far-Field Tomography of a Bulk Skyrmion Lattice

August 13, 2023

Melissa Henderson, Benjamin Heacock, Markus Bleuel, David Cory, Colin Heikes, Michael G. Huber, Jeffery Krzywon, Olivier Nahman-Levesque, Graeme Luke, M Pula, Dusan Sarenac, Kirill Zhernenkov, Dmitry Pushin
Magnetic skyrmions are localized non-collinear spin textures, characterized by an integer topo-logical charge. Their nanometric size and topological protection gives rise to unique dynamics and emergent electromagnetic phenomena, ideal for spintronic

Spin-orbit coupling of light has come to the fore in nano-optics and plasmonics, and is a key ingredient of topological photonics and chiral quantum optics. We demonstrate a basic tool for incorporating analogous effects into neutron optics: the generation

The neutron spin-orbit interaction, which results from the interaction of a moving neutron's magnetic dipole moment (MDM) with the atomic electric elds, induces a small rotation of the neutron's spin in one Bragg re ection. In our experiment neutrons

The generation and control of neutron orbital angular momentum (OAM) states and spin correlated OAM (spin-orbit) states provides a powerful probe of materials with unique penetrating abilities and magnetic sensitivity. We describe techniques to prepare and

We find that annealing a previously chemically etched interferometer at 800 °C dramatically increased the interference fringe visibility from 23 % to 90 %. The Bragg plane misalignments were also measured before and after annealing using neutron rocking
