Current-induced domain wall motion in the presence of the Dzyaloshinskii-Moriya interaction (DMI) is experimentally and theoretically investigated in heavy-metal/ferromagnet bilayers. The angular dependence of the current-induced torque and the magnetization structure of Dzyaloshinskii domain walls are described and quantified simultaneously in the presence of in-plane fields. We show that the DMI strength depends strongly on the heavy metal, varying by a factor of 20 between Ta and Pa, and that strong DMI leads to wall distortions not seen in conventional materials. These findings provide essential insights for understanding and exploiting chiral magnetism for emerging spintronics applications.

“…This contrasts with the observations of Wyslocki and Zietek (1969) also on cobalt crystals, but with thicknesses greater than 5 pm, where the 'honeycomb' nature of the domains was evident. In addition, the observations of Kaczer and Gemperle (1961) and Gemperle (1964) on magnetoplumbite crystals, of thickness varying from 1-400 pm, showed an increasing distortion of the domains with increasing thickness. On the basis of these results it appears that the prediction of equation (1 1) …”

“…Measurements were made on the photographs published by Kaczer and Gemperle (1961) and Gemperle (1964) for magnetoplumbite and Wyslocki and Zietek (1969) for cobalt to obtain a very approximate value for Arslro. Using this value, which corresponds to film thicknesses of about 20 pm, in equation (12), gives E~/ET 0.05.…”

“…In spite of these postulations, honeycomb domains have been observed in films in zero field, as have bubble domains. Particular attention is drawn to cobalt, where strip and bubble (Grundy et al 1971) as well as honeycomb domains (Wyslocki and Zietek 1969) have been observed and to magnetoplumbite, where similar observations have been made by Kaczer and Gemperle (1961) and Gemperle (1964). This situation merits some discussion and this is now given.…”

Bloch Lines Constituting Antiskyrmions Captured via Differential Phase Contrast

et al. 2020

Much scientific capital has been directed toward exotic magnetic spin textures called Bloch lines, that is, Néel‐type line boundaries within domain walls, because their geometry promises high‐density magnetic storage. While predicted to arise in high‐anisotropy magnets, bulk soft magnets, and thin films with in‐plane magnetization, Bloch lines also constitute magnetic antiskyrmions, that is, topological antiparticles of skyrmions. Most domain walls occur as Bloch‐type or Néel‐type, in which the magnetization rotates parallel or perpendicular to the domain wall across its profile, respectively. The Bloch lines’ Néel‐type rotation and their minute size make them difficult to directly measure. This work utilizes differential phase contrast (DPC) scanning transmission electron microscopy (STEM) to measure the in‐plane magnetization of Bloch lines within antiskyrmions emergent in a non‐centrosymmetric Heusler magnet with D2d symmetry, Mn1.4Pt0.9Pd0.1Sn, in addition to Bloch‐type skyrmions in an FeGe magnet with B20‐type crystal structure to benchmark the DPC technique. Both in‐focus measurement and identification of Bloch lines at the antiskyrmion's corners are provided.
