Spontaneous square vs. hexagonal nanoscale skyrmion lattices in Fe/Ir(111)

Mara Gutzeit, Tim Drevelow, Moritz A. Goerzen +2

We study the emergence of spontaneous skyrmion lattices in an Fe monolayer in fcc and hcp stacking on the Ir(111) surface using density functional theory (DFT). For fcc-Fe/Ir(111)…
