Spin-wave eigenmodes in direct-write 3D nanovolcanoes
O. V. Dobrovolskiy, N. R. Vovk, A. V. Bondarenko +9
Extending nanostructures into the third dimension has become a major research avenue in modern magnetism, superconductivity and spintronics, because of geometry-, curvature- and to…
Engineered magnetization and exchange stiffness in direct-write Co-Fe nanoelements
S. A. Bunyaev, B. Budinska, R. Sachser +10
Media with engineered magnetization are essential building blocks in superconductivity, magnetism and magnon spintronics. However, the established thin-film and lithographic techni…
Transient dynamics of strongly coupled spin vortex pairs: effects of anharmonicity and resonant excitation on inertial switching
E. Holmgren, A. Bondarenko, M. Persson +2
Spin vortices in magnetic nanopillars are used as GHz oscillators, with frequency however essentially fixed in fabrication. We demonstrate a model system of a two-vortex nanopillar…
Chaotic dynamics in spin-vortex pairs
A. V. Bondarenko, E. Holmgren, Z. W. Li +2
We report on spin-vortex pair dynamics measured at temperatures low enough to suppress stochastic core motion, thereby uncovering the highly non-linear intrinsic dynamics of the sy…
Resonant pinning spectroscopy with spin-vortex pairs
E. Holmgren, A. Bondarenko, B. A. Ivanov +1
Vortex pairs in magnetic nanopillars with strongly coupled cores and pinning of one of the cores by a morphological defect, are used to perform resonant pinning spectroscopy, in wh…
Static and dynamic properties of vortex pairs in asymmetric nanomagnets
B. C. Koop, M. Gruschke, T. Descamps +3
Stacked spin-vortex pairs in magnetic multilayered nanopillars, with vertical separation between the vortices small compared to the vortex core size, exhibit spin dynamics absent i…
