Dynamic annihilation pathways of magnetic skyrmions
Matthew Copus, Ezio Iacocca
The investigation of magnetic solitons often relies on numerical modeling to determine key features such as stability, annihilation, nucleation, and motion. However, as soliton siz…
Controllable vortex shedding from dissipative exchange flows in ferromagnetic channels
Ezio Iacocca
Ferromagnetic channels subject to spin injection at one extremum sustain long-range coherent textures that carry spin currents known as dissipative exchange flows (DEFs). In the we…
Tailoring spin wave channels in a reconfigurable artificial spin ice
Ezio Iacocca, Sebastian Gliga, Olle Heinonen
Artificial spin ices are ensembles of geometrically-arranged, interacting nanomagnets which have shown promising potential for the realization of reconfigurable magnonic crystals.…
Hydrodynamic description of long-distance spin transport through noncollinear magnetization states: the role of dispersion, nonlinearity, and damping
Ezio Iacocca, Mark A. Hoefer
Nonlocal compensation of magnetic damping by spin injection has been theoretically shown to establish dynamic, noncollinear magnetization states that carry spin currents over micro…
Spin-current-mediated rapid magnon localisation and coalescence after ultrafast optical pumping of ferrimagnetic alloys
E. Iacocca, T-M. Liu, A. H. Reid +31
Sub-picosecond magnetisation manipulation via femtosecond optical pumping has attracted wide attention ever since its original discovery in 1996. However, the spatial evolution of…
