Room temperature magnetic vortices in the van der Waals magnet Fe${}_5$GeTe${}_2$

Elias Sfeir, Carolin Schrader, Florentin Fabre +8

We investigate the effect of confinement on the magnetic state of a 12 nm-thick Fe${}_5$GeTe${}_2$ layer grown by molecular beam epitaxy. We use quantitative scanning NV magnetometry t…
