Wave dynamics in a macroscopic square artificial spin ice
L. Scafuri, D. A. Bozhko, E. Iacocca
A macroscopic square artificial spin ice, or macro-ASI, is a collection of bar magnets placed in a square lattice arrangement. Each magnet is supported by hinges that allow their m…
Dynamics of metastable contact soliton dissipative exchange flows in one-dimensional ferromagnetic channels
Medhanie Estiphanos, Ezio Iacocca
Dissipative exchange flows (DEFs) are large-amplitude boundary value solutions of ferromagnetic channels. In their low-injection limit, DEFs reduce to spin superfluids. However, in…
Frequency comb in a macroscopic mechano-magnetic artificial spin ice
Renju R. Peroor, Lawrence Scafuri, Dmytro A. Bozhko +1
Artificial spin ices are metamaterials composed of interacting nanomagnets exhibiting frustration. Their resonant magnetization dynamics have been broadly investigated from fundame…
Contact solitons as spin pistons in one-dimensional ferromagnetic channels
Medhanie Estiphanos, Ezio Iacocca
Ferromagnetic channels subject to spin injection have been theoretically shown to sustain dissipative exchange flows (DEFs). In the strong injection regime, a soliton is stabilized…
Ferromagnetic resonance in 3D-tilted square artificial spin ices
Ghanem Alatteili, Alison Roxburgh, Ezio Iacocca
Artificial spin ices (ASIs) arranged in square formations have been explored from the perspective of reconfigurable magnonics. A new frontier in ASIs is their three-dimensional (3D…
