Formation and stability of metastable skyrmionic spin structures with various topologies in an ultrathin film
We observe metastable localized spin configurations with topological charges
ranging from to in a (PtIr)/Fe bilayer on
Pd surface by performing spin dynamics simulations, using a classical
Hamiltonian parametrized by ab initio calculations. We demonstrate that the
frustration of the isotropic exchange interactions is responsible for the
creation of these various types of skyrmionic structures. The
Dzyaloshinsky--Moriya interaction present due to the breaking of inversion
symmetry at the surface energetically favors skyrmions with , distorts
the shape of the other objects, and defines a preferred orientation for them
with respect to the underlying lattice.Comment: 9 pages manuscript, 3 figures, 4 table
