TetMaG-Guided Design and Operando Electron Holography Validation of Current-Induced Domain-Wall Motion in 3D Curved and Cornered Fe Nanobridges
Sameh Okasha, Shriyar Tariq, Attila Kákay +4
Three-dimensional (3D) magnetic nanostructures offer new opportunities for controlling domain-wall (DW) configurations beyond the limitations of planar systems, providing promising…
Exchange-dominated frequency shift of spin-wave nonreciprocal dispersion relation in planar magnetic multilayers
Claudia Negrete, Attila Kákay, Jorge A. Otálora
Spin-wave nonreciprocity, manifested as a frequency difference between counterpropagating modes, underpins many proposed magnonic devices. While this effect is commonly attributed…
Nanoscale magnetometry of a synthetic three-dimensional spin texture
Ricardo Javier Peña Román, Sandip Maity, Fabian Samad +7
Multilayered synthetic antiferromagnets (SAFs) are artificial three-dimensional (3D) architectures engineered to create novel, complex, and stable spin textures. Non-invasive and q…
Coherent control of Floquet-engineered magnon frequency combs
Christopher Heins, Amelie L. Fehrmann, Lukas Körber +5
Frequency combs represent a hallmark of coherence emerging from nonlinear dynamics, where periodic driving organizes energy into a precisely spaced spectral structure. Extending th…
Controlling the Spin-Wave Nonreciprocity of a Crescent-Shaped Nanowire via Curvature and Magnetic Field
Uladzislau Makartsou, Mateusz Gołębiewski, Attila Kákay +2
Recent studies on spin-wave propagation in ferromagnetic waveguides has highlighted the role of nonreciprocity resulting from the chiral nature of dipolar interactions in curved el…
Electrical magnon spectroscopy with foundry-fabricated nanoscale magnetic tunnel junctions
Christopher Heins, Zeling Xiong, Attila Kákay +10
Magnonics uses spin waves and their quanta, magnons, to carry and process information and offers new opportunities for computing and signal processing. Its integration with convent…
Control of magnon frequency combs in magnetic rings
Christopher Heins, Attila Kákay, Joo-Von Kim +4
Using Brillouin light scattering microscopy, we study the rich dynamics in magnetic disks and rings governed by non-linear interactions, focusing on the role of vortex core dynamic…
Toroidal Moments in Confined Nanomagnets and their Impact on Magnonics
Felipe Brevis, Lukas Körber, B. Mimica-Figari +3
The nonreciprocity created by dipolar coupling, electric currents, and Dzyaloshinskii-Moriya interactions is discussed in cases where the magnon propagation direction has a compone…
