Magnetoelastic coupling in stripe-domain states of yttrium iron garnet
Nimisha Arora, Daniel Prestwood, Takashi Kikkawa +4
We study magnetoelastic coupling in stripe-domain magnetic states of -thick YIG thin films grown on a GGG substrate. Broadband ferromagnetic resonance reveals low-f…
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…
Learning Nonlinear Heterogeneity in Physical Kolmogorov-Arnold Networks
Fabiana Taglietti, Andrea Pulici, Maxwell Roxburgh +10
Physical neural networks typically train linear synaptic weights while treating device nonlinearities as fixed. We show the opposite - by training the synaptic nonlinearity itself,…
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…
Synthetic spin-orbit coupling in superconductor-semiconductor hybrid nanowires with micromagnet arrays
M. P. Hynes, D. Burke, K. Ganesh +9
Spin-orbit interaction accounts for the coupling of momentum and spin degrees of freedom of electrons and holes in semiconductor materials. In quantum information processing, it al…
