Experimental synthesis and validation of magnetic Hopfions through observation of their characteristic three-dimensional (3D) spin texture using a combination of surface and bulk-sensitive X-ray microscopy techniques
Significance and Impact
Confirmed theoretical predictions of magnetic Hopfions. The work will stimulate further experimental studies towards the potential applications of Hopfions in 3D spintronics
- Asymmetric magnetic (Ir/Co/Pt) multilayers were patterned by e-beam lithography into nanopillars
- A combined magnetic X-ray photoemission and transmission soft x-ray microscopy study revealed characteristic spin textures confirming the creation of a magnetic Hopfion.
- Theoretical simulations guided design of multilayer stack’s PMA values to stabilize magnetic Hopfions
