Brillouin Light Scattering Spectroscopy of Propagating Magnons at Sub-Kelvin Temperatures
David Schmoll, Nikolai Kuznetsov, Phillip Rehberger +8
Coupling light to magnetic excitations in the form of spin waves underpins both the optical study of magnetism and emerging schemes for quantum transduction, positioning the quanta…
Spin-Wave Phase Shifter Controlled by a Domain Wall Racetrack
Uladzislau Makartsou, Olena Tartakivska, PaweÅ Gruszecki +4
We propose a spin-wave phase shifter controlled using a domain-wall racetrack. The concept is demonstrated using micromagnetic simulations of a Permalloy domain-wall racetrack plac…
Spin-wave bandgap engineering via mode hybridization in dipolar-coupled YIG film/CoFeB nanodisk magnonic crystals
Junyoung Hyun, Krzysztof Szulc, Mateusz Zelent +5
We investigate spin-wave transport in hybrid two-dimensional magnonic crystals comprising a low-damping yttrium iron garnet (YIG) film coupled to a periodic array of CoFeB nanodisk…
Bismuth-substituted Lutetium Iron Garnet Films with Giant Visible-Range Magneto-Optical Sensitivity
Megan H. Dransfield, Matthijs H. J. de Jong, Lukáš Flajšman +6
Magneto-optical materials are indispensable across modern physics, serving as the foundation for precision magnetic sensing, nonreciprocal photonics, and optical isolation technolo…
Nonlinear dynamics in magnonic Fabry-Pérot resonators: Low-power neuron-like activation and transmission suppression
Anton Lutsenko, Kevin G. Fripp, Lukáš Flajšman +3
We report on nonlinear spin-wave dynamics in magnonic Fabry-Pérot resonators composed of yttrium iron garnet (YIG) films coupled to CoFeB nanostripes. Using super-Nyquist sampling…
A magneto-ionic synapse for reservoir computing
Sreeveni Das, Rhodri Mansell, Lukáš Flajšman +3
Neuromorphic computing aims to revolutionize large-scale data processing by developing efficient methods and devices inspired by neural networks. Among these, the control of magnet…
