We present a comparison of the characteristics of magnetic domain walls in an atomic monolayer of Co on Pt(111) and a Ni/Fe atomic bilayer on Ir(111) based on spin-polarized scanning tunneling microscopy measurements. In both cases, the films exhibit a roughly triangular dislocation line pattern created by epitaxial strain relief, as well as out-of-plane ferromagnetic order. Domains with opposite magnetization are separated by domain walls with a unique rotational sense, demonstrating the… Expand

Domain wall pinning on strain relaxation defects in FePt(001)/Pt thin films
Thin FePt (001) films, grown by molecular-beam epitaxy on Pt(001), exhibit a very large perpendicular magnetic anisotropy (Ku=5×106 J m−3) and a 100% magnetic remanence in perpendicular field. TheExpand
Domain-wall pinning by local control of anisotropy in Pt/Co/Pt strips.
Varying the thickness of the Co layer provides an additional way to tune the anisotropy, and it is shown that a thinner Co layer gives a higher starting anisOTropy thereby allowing tunable DW pinning in a wider range of fields. Expand
Thin films of Co on Pt(111): Strain relaxation and growth
The growth, structure and morphology of thin Co layers with a thickness ranging from 1 to 15 monolayers deposited at room temperature on Pt ~111! have been studied by the use of scanning tunnelingExpand
An atomic-scale study of the Co induced dendrite formation on Pt(111)
Abstract We have studied the initial growth of Co on the Pt(111) surface in a temperature range of 300–400 K with scanning tunneling microscopy, low energy ion scattering and Auger electronExpand
Chirality-Induced asymmetric magnetic nucleation in Pt/Co/AlOx ultrathin microstructures.
The nucleation of reversed magnetic domains in Pt/Co/AlO(x) microstructures with perpendicular anisotropy was studied experimentally in the presence of an in-plane magnetic field and it was observed to depend in a chiral way on the initial magnetization and applied field directions. Expand
Pinning effect of the grain boundaries on magnetic domain wall in FeCo-based magnetic alloys
We have studied the dynamics of grain growth and the pinning effect of grain boundaries on magnetic domain walls in FeCo soft magnetic alloys. It has been found that grain growth takes place atExpand
Competition of Dzyaloshinskii-Moriya and Higher-Order Exchange Interactions in Rh/Fe Atomic Bilayers on Ir(111).
Using spin-polarized scanning tunneling microscopy and density functional theory, a novel type of noncollinear spin structure in Rh/Fe atomic bilayers on Ir(111) is demonstrated and it is found that higher-order exchange interactions depend sensitively on the stacking sequence. Expand
Dynamics of Dzyaloshinskii domain walls in ultrathin magnetic films
We explore a new type of domain wall structure in ultrathin films with perpendicular anisotropy, that is influenced by the Dzyaloshinskii-Moriya interaction due to the adjacent layers. This study isExpand
Dzyaloshinskii-Moriya interaction accounting for the orientation of magnetic domains in ultrathin films: Fe/W(110)
Combining relativistic first-principles calculations with a micromagnetic model, we establish the Dzyaloshinskii-Moriya interaction as an important mechanism in thin-film magnetism, determining theExpand
