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…
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…
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…
Controlling the Spin-Wave Nonreciprocity of a Crescent-Shaped Nanowire via Curvature and Magnetic Field
Uladzislau Makartsou, Mateusz GoÅÄbiewski, 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…
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…
Electrical detection of magnons with nanoscale magnetic tunnel junctions
Christopher Heins, Zeling Xiong, Attila Kákay +10
Present information and communication technologies are largely based on electronic devices, which suffer from heat generation and high power consumption. Alternatives like spintron…
