Beyond conventional skyrmions in synthetic antiferromagnets
Kayla Fallon, Reshma Peremadathil-Pradeep, Christopher E. A. Barker +14
Magnetic skyrmions are topologically protected spin textures that can act as reconfigurable nanoscale information carriers. In synthetic antiferromagnets (SAFs), interlayer exchang…
Cavity modification of magnetoplasmon mode through coupling with intersubband polaritons

We investigate the coupling of a multi-mode metal-insulator-metal cavity to a two-dimensional electron gas (2DEG) in a quantum well in the presence of a strong magnetic field. The…
Observing Differential Spin Currents by Resonant Inelastic X-ray Scattering
Yanhong Gu, Joseph Barker, Jiemin Li +12
Controlling spin currents, i.e., the flow of spin angular momentum, in small magnetic devices is the principal objective of spin electronics, a main contender for future energy eff…
Low-energy, ultrafast spin reorientation at competing hybrid interfaces with tunable operating temperature
Servet Ozdemir, Matthew Rogers, Jaka Strohsack +12
Information can be stored in magnetic materials by encoding with the direction of the magnetic moment of elements. A figure of merit for these systems is the energy needed to chang…
Demagnetization in micromagnetics: magnetostatic self-interactions of bulk chiral magnetic skyrmions
Paul Leask, Martin Speight
We develop a theoretical and numerical framework for three-dimensional bulk chiral magnets that includes the full magnetostatic dipole-dipole interaction and its back-reaction on t…

Mairi McCauley, Lida Ansari, Farzan Gity +8
Topological Insulators (TIs) present an interesting materials platform for nanoscale, high frequency devices because they support high mobility, low scattering electronic transport…
Materials for Quantum Technologies: a Roadmap for Spin and Topology
N. Banerjee, C. Bell, C. Ciccarelli +22
In this Perspective article, we explore some of the promising spin and topology material platforms (e.g. spins in semi- and superconductors, skyrmionic, topological and 2D material…
Fingerprints of Composite Fermion Lambda Levels in Scanning Tunneling Microscopy
Songyang Pu, Ajit C. Balram, Yuwen Hu +6
Composite fermion (CF) is a topological quasiparticle that emerges from a non-perturbative attachment of vortices to electrons in strongly correlated two-dimensional materials. Sim…
High-Resolution Tunneling Spectroscopy of Fractional Quantum Hall States
Yuwen Hu, Yen-Chen Tsui, Minhao He +8
Strong interaction between electrons in two-dimensional systems in the presence of a high magnetic field gives rise to fractional quantum Hall states that host quasiparticles with…
