Correlation and spin texture in two dimensional materials News from Michely STM group at University of Cologne Tweets by Jeison Fischer (junior researcher)
Joined February 2023
Thrilled to announce our new paper @NanoLetters We demonstrate an elegant, non-volatile way to transform an exchange-driven spin spiral into elliptical skyrmions under lab-scale magnetic fields — all enabled by hydrogen. Check it out below. https://t.co/sOWir0cQp6
pubs.acs.org
Skyrmions are particle-like spin textures that arise from spin spiral states in an external magnetic field. These spirals can originate from frustrated Heisenberg exchange or from the interplay of...
