Realistic micromagnetic description of all-optical ultrafast switching processes in ferrimagnetic alloys
V. Raposo, F. García-Sánchez, U. Atxitia +1
Both helicity-independent and helicity-dependent all-optical switching processes driven by single ultrashort laser pulse have been experimentally demonstrated in ferrimagnetic allo…
Domain Wall Motion in Magnetic Nanostrips
Oscar Alejos, Víctor Raposo, Eduardo Martínez
Domain walls are the transition regions between two magnetic domains. These objects have been very relevant during the last decade, not only due to their intrinsic interest in the…
Current-driven domain wall dynamics in ferromagnetic layers synthetically exchange-coupled by a spacer: A micromagnetic study
Oscar Alejos, Victor Raposo, Luis Sanchez-Tejerina +3
The current-driven domain wall motion along two exchange-coupled ferromagnetic layers with perpendicular anisotropy is studied by means of micromagnetic simulations and compared to…
Efficient and controlled domain wall nucleation for magnetic shift registers
Oscar Alejos, Victor Raposo, Luis Sanchez-Tejerina +1
Ultrathin ferromagnetic strips with high perpendicular anisotropy have been proposed for the development of memory devices where the information is coded in tiny domains separated…
Current induced generation and synchronous motion of highly packed coupled chiral domain walls
Rafael P. del Real, Victor Raposo, Eduardo Martinez +1
Chiral domain walls of Neel type emerge in heterostructures that include heavy metal (HM) and ferromagnetic metal (FM) layers owing to the Dzyaloshinskii-Moriya (DM) interaction at…
Domain wall motion by localized temperature gradients
Simone Moretti, Victor Raposo, Eduardo Martinez +1
Magnetic domain wall (DW) motion induced by a localized Gaussian temperature profile is studied in a Permalloy nanostrip within the framework of the stochastic Landau-Lifshitz-Bloc…
Influence of Joule heating on current-induced domain wall depinning
Simone Moretti, Victor Raposo, Eduardo Martinez
The domain wall depinning from a notch in a Permalloy nanostrip on top of a substrate is studied theoretically under application of static magnetic fields and the…
Universal chiral-triggered magnetization switching in confined nanodots
Eduardo Martinez, Luis Torres, Noel Perez +3
Spin orbit interactions are rapidly emerging as the key for enabling efficient current-controlled spintronic devices. Much work has focused on the role of spin-orbit coupling at he…
