Few-Shot Neuromorphic Vision in a Nonlinear Photonic Network Laser
Wai Kit Ng, Jakub Dranczewski, Anna Fischer +11
With the growing prevalence of AI, demand increases for hardware that mimics the brain's ability to extract structure from limited data. In the retina, ganglion cells detect featur…
Dynamical stability by spin transfer in nearly isotropic magnets
Hidekazu Kurebayashi, Joseph Barker, Takumi Yamazaki +9
Spin transfer torques (STTs) control magnetisation by electric currents, enabling a range of nano-scale spintronic applications. They can destabilise the equilibrium magnetisation…
Spin wave resonance in yttrium iron garnet stripe domains
Daniel Prestwood, Chris E. A. Barker, Kilian D. Stenning +15
We study a thin film yttrium iron garnet sample that exhibits magnetic stripe domains due to a small perpendicular magnetic anisotropy. Using wide-field magneto-optic Kerr effect m…
Magnetic vortex writing and local reversal seeding in artificial spin-vortex ice via all-optical and surface-probe control
Holly Holder, Jack C. Gartside, Alex Vanstone +8
Artificial spin-vortex ice ('ASVI') is a reconfigurable nanomagnetic metamaterial consisting of magnetic nanoislands tailored to support both Ising macrospin and vortex textures. A…
Artificial Spin Ice: A Tutorial on Design and Control of Geometry, Microstate, Magnon Dynamics & Neuromorphic Computing
Rawnak Sultana, Amrit Kumar Mondal, Vinayak Shantaram Bhat +9
Artificial spin ice, arrays of strongly interacting nanomagnets, are complex magnetic systems with many emergent properties, rich microstate spaces, intrinsic physical memory, high…
