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…
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.…
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…
