Journal ArticleDOI
Stable magnetic droplet solitons in spin-transfer nanocontacts
TL;DR: It is shown that magnetic droplet solitons exhibit a strong hysteretic response in field and current, proving the existence of bistable states: droplet and non-droplet states.
Journal ArticleDOI
Spin-wave interference patterns created by spin-torque nano-oscillators for memory and computation.
TL;DR: This work shows how arrays of spin-torque nano-oscillators can create propagating spin-wave interference patterns of use for memory and computation and groups of transponders create resonant (reverberating) spin- wave interference patterns that may be used for polychronous wave computation and information storage.
Journal ArticleDOI
Direct imaging of delayed magneto-dynamic modes induced by surface acoustic waves
Michael Foerster,Ferran Macià,Ferran Macià,Nahuel Statuto,Nahuel Statuto,Simone Finizio,Simone Finizio,Alberto Hernández-Mínguez,Sergi Lendinez,Paulo V. Santos,Josep Fontcuberta,Joan Manel Hernàndez,Mathias Kläui,Lucia Aballe +13 more
TL;DR: Foerster et al. as mentioned in this paper studied the effect of dynamic strain accompanying a surface acoustic wave on magnetic nanostructures in thermal equilibrium and showed that magnetization modes have a delayed response to the strain modes, adjustable by the magnetic domain configuration.
Journal ArticleDOI
Direct observation and imaging of a spin-wave soliton with p-like symmetry
Stefano Bonetti,Roopali Kukreja,Zhao Chen,Zhao Chen,Ferran Macià,Joan Manel Hernàndez,Anders Eklund,Dirk Backes,Josef Frisch,Jordan A. Katine,Gunnar Malm,Sergei Urazhdin,Andrew D. Kent,Joachim Stöhr,Hendrik Ohldag,H. A. Dürr +15 more
TL;DR: Micromagnetic simulations explain the measurements and reveal that the symmetry of the soliton can be controlled by magnetic fields, which broadens the understanding of spin-wave dynamics at the nanoscale, with implications for the design of magnetic nanodevices.

Direct Observation of a Localized Magnetic Soliton in a Spin-Transfer Nanocontact
Dirk Backes,Ferran Macià,Ferran Macià,Stefano Bonetti,Stefano Bonetti,Roopali Kukreja,Roopali Kukreja,Hendrik Ohldag,Hendrik Ohldag,Andrew D. Kent +9 more
TL;DR: In this article, the authors reported the direct observation of a localized magnetic soliton in a spin-transfer nanocontact using scanning transmission x-ray microscopy, but the amplitude of the excitation ≃25° at the contact center was far less than that predicted (⪅180°), showing that spin dynamics is not described by existing models.
