Deterministically switching the Bloch chirality of domain walls and skyrmions: the Dzyaloshinskii astroid
Michael Kitcher, Larry Chen, Marc De Graef +1
We present a mechanism for deterministic control of the Bloch chirality in magnetic domain walls and skyrmions, originating from the interplay between an interfacial Dzyaloshinskii…
Towards hexagonal systems with anisotropic DMI: Characterization of epitaxial Co/Pt multilayer films
Yukun Liu, Michael D. Kitcher, Marc De Graef +1
Ferromagnet/heavy metal (FM/HM) multilayer thin films with symmetry have the potential to host antiskyrmions and other chiral spin textures via an anisotropic Dzyaloshinki…
Direct observation of topological charge impacting skyrmion bubble stability in Pt/Ni/Co asymmetric superlattices
Nisrit Pandey, Maxwell Li, Marc De Graef +1
We characterize the magnetic properties and domain structure of Pt/Ni/Co asymmetric superlattices in comparison to the more established Pt/Co/Ni structure. This reversal in stackin…
Magnetic Nanohorns for measurement of the interfacial Dzyaloshinskii-Moriya interaction: A micromagnetic study
Thomas Wong, Vincent Sokalski
We evaluate the micromagnetic energy of a domain wall contained in a thin, horn-shaped nanostructure and propose a method to extract the strength of the interfacial Dzyaloshinskii-…
Dynamic symmetry breaking in chiral magnetic systems
Jeffrey A. Brock, Michael D. Kitcher, Pierre Vallobra +6
The Dzyaloshinskii-Moriya interaction (DMI) in magnetic systems stabilizes spin textures with preferred chirality, applicable to next-generation memory and computing architectures.…
Magnetic domain wall substructures in Pt/Co/Ni/Ir multi-layers
Maxwell Li, Arjun Sapkota, Anish Rai +6
We examine the substructures of magnetic domain walls (DWs) in [Pt/(Co/Ni)/Ir] multi-layers using a combination of micromagnetic theory and Lorentz transmission electron mi…
Formation of zero-field Skyrmion arrays in asymmetric superlattices
Maxwell Li, Anish Rai, Ashok Pokhrel +5
We demonstrate the formation of metastable Néel-type skyrmion arrays in Pt/Co/Ni/Ir multi-layers at zero-field following \textit{ex situ} application of an in-plane magnetic field…
Stabilization of coupled Dzyaloshinskii domain walls in fully compensated synthetic anti-ferromagnets
Nisrit Pandey, Maxwell Li, Marc De Graef +1
We examine the combined effects of interlayer exchange coupling (IEC) and the interfacial Dzyaloshinskii-Moriya Interaction (DMI) on the structure of magnetic domain walls in fully…
Lorentz TEM investigation of chiral spin textures and Néel Skyrmions in asymmetric [Pt/(Co/Ni)/Ir] multi-layer thin films
Maxwell Li, Derek Lau, Marc De Graef +1
We examine magnetic domain patterns in symmetric [Co/Ni] and asymmetric [Pt/(Co/Ni)/Ir] multi-layers using Fresnel mode Lorentz transmission electron microscopy (LTEM).…
Magnetic domain wall Skyrmions
Ran Cheng, Maxwell Li, Arjun Sapkota +7
It is well established that the spin-orbit interaction in heavy metal/ferromagnet heterostructures leads to a significant interfacial Dzyaloshinskii-Moriya Interaction (DMI) that m…
Disentangling factors governing Dzyaloshinskii domain wall creep in Co/Ni thin films using PtIr seedlayers

We characterize asymmetric growth of magnetic bubble domains in perpendicularly magnetized Co/Ni multi-layers grown on PtIr seedlayers by application of perpendicular a…
Dispersive Stiffness of Dzyaloshinskii Domain Walls

It is well documented that subjecting perpendicular magnetic films which exhibit the interfacial Dzyaloshinskii-Moriya interaction (DMI) to an in-plane magnetic field results in a…
Energetic molding of chiral magnetic bubbles
Derek Lau, Vignesh Sundar, Jian-Gang Zhu +1
Topologically protected magnetic structures such as skyrmions and domain walls (DWs) have drawn a great deal of attention recently due to their thermal stability and potential for…
