Impacts of the half-skyrmion spin topology, spin-orbit torque, and dynamic symmetry breaking on the growth of magnetic stripe domains
Jeffrey A. Brock, Daan Swinkels, Bert Koopmans +1
We have performed an experimental and modeling-based study of the spin-orbit torque-induced growth of magnetic stripe domains in heavy metal/ferromagnet thin-film heterostructures…
Evidence of extreme domain wall speeds under ultrafast optical excitation
Rahul Jangid, Nanna Zhou Hagström, Meera Madhavi +14
Time-resolved ultrafast EUV magnetic scattering was used to test a recent prediction of >10 km/s domain wall speeds by optically exciting a magnetic sample with a nanoscale labyrin…
Quantum sensing and imaging of spin-orbit-torque-driven spin dynamics in noncollinear antiferromagnet Mn3Sn
Gerald Q. Yan, Senlei Li, Hanyi Lu +8
Novel noncollinear antiferromagnets with spontaneous time-reversal symmetry breaking, nontrivial band topology, and unconventional transport properties have received immense resear…
Symmetry-dependent ultrafast manipulation of nanoscale magnetic domains
Nanna Zhou Hagström, Rahul Jangid, Meera +25
Symmetry is a powerful concept in physics, but its applicability to far-from-equilibrium states is still being understood. Recent attention has focused on how far-from-equilibrium…
Non-equilibrium self-assembly of spin-wave solitons in FePt nanoparticles
D. Turenne, A. Yaroslavtsev, X. Wang +36
Magnetic nanoparticles such as FePt in the L10-phase are the bedrock of our current data storage technology. As the grains become smaller to keep up with technological demands, the…
Skyrmion stabilization at the domain morphology transition in ferromagnet/heavy metal heterostructures with low exchange stiffness
Jeffrey A. Brock, Eric E. Fullerton
We report the experimental observation of micron-scale magnetic skyrmions at room temperature in several Pt/Co-based thin film heterostructures designed to possess a low exchange s…
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.…
Energy-efficient generation of skyrmion phases in Co/Ni/Pt-based multilayers using Joule heating
Jeffrey A. Brock, Sergio A. Montoya, Mi-Young Im +1
We have studied the effects of electrical current pulses on skyrmion formation in a series of Co/Ni/Pt-based multilayers. Transmission X-ray microscopy reveals that by applying ele…
