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…
Absence of Walker breakdown in the dynamics of chiral Neel domain walls driven by in-plane strain gradients
Mouad Fattouhi, Felipe Garcia-Sanchez, Rocio Yanes +3
We investigate theoretically the motion of chiral Néel domain walls in perpendicularly magnetized systems driven by in-plane strain gradients. We show that such strain drives domai…
Novel interpretation of recent experiments on the dynamics of domain walls along ferrimagnetic strips
Eduardo Martínez, Víctor Raposo, Óscar Alejos
Domain wall motion along ferrimagnets is evaluated using micromagnetic simulations and a collective-coordinates model, both considering two sublattices with independent parameters.…
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…
