The large epitaxial stress induced by the misfit between a triple atomic layer Fe film and an Ir(111) substrate is relieved by the formation of a dense dislocation line network. Spin-polarized scanning tunneling microscopy investigations show that the strain is locally varying within the Fe film and that this variation affects the magnetic state of the system. Two types of dislocation line regions can be distinguished and both exhibit spin spirals with strain-dependent periods (ranging from 3… Expand

Non-collinear Magnetism Studied with Spin-Polarized Scanning Tunneling Microscopy
Non-collinear magnetic states in nanostructures and ultra thin films have moved into the focus of research upon the experimental discovery that the interface -induced Dzyaloshinskii–MoriyaExpand
Interplay between non-collinear magnetism and nanoscale structural properties in epitaxial Fe-based ultrathin films
In view of creating devices taking advantage of the properties of non-collinear magnetic states in ultrathin films, the ability to stabilize and reliably control them is essential. In particular,Expand
Skyrmions on 2D elastic surfaces with fixed boundary frame
We report simulation results of skyrmions on fluctuating 2D lattices, where the vertices ${\bf r}_i (\in {\bf R}^3)$ are treated as a dynamical variable and, hence, there is no crystalline structure.Expand
Temperature-Induced Increase of Spin Spiral Periods.
A classical spin model is proposed that reproduces the experimental observations and in which the crucial feature is the presence of magnetically coupled atomic layers with different interaction strengths, which might also apply for many other systems, especially magnetic multilayers. Expand
Dzyaloshinskii-Moriya interaction at disordered interfaces from ab initio theory: Robustness against intermixing and tunability through dusting
The Dzyaloshinskii-Moriya interaction (DMI), which is essential for the stabilization of topologically non-trivial chiral magnetic textures such as skyrmions, is particularly strong inExpand
