Formation and stability of metastable skyrmionic spin structures with various topologies in an ultrathin film

Levente Rózsa, Krisztián Palotás, András Deák +5

We observe metastable localized spin configurations with topological charges ranging from $Q=-3$ to $Q=2$ in a (Pt${}_{0.95}$Ir${}_{0.05}$)/Fe bilayer on Pd$(111)$ surface by performin…
