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…
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…
