Intrinsic excitations and a proposed ground state in an Ammann-Beenker artificial spin ice
E Weightman, L O'Brien, S Coates
Artificial spin ices built on quasiperiodic geometries remain under-explored. Here we investigate an ASI based on the octagonal Ammann-Beenker tiling, whose six vertex types presen…

Entropy-driven order in an array of nanomagnets
Hilal Saglam, Ayhan Duzgun, Aikaterini Kargioti +14
Long-range ordering is typically associated with a decrease in entropy. Yet, it can also be driven by increasing entropy in certain special cases. We demonstrate that artificial sp…

Coupling and induced depinning of magnetic domain walls in adjacent spin valve nanotracks
J. Sampaio, L. O'Brien, D. Petit +6
The magnetostatic interaction between magnetic domain walls (DWs) in adjacent nanotracks has been shown to produce strong inter-DW coupling and mutual pinning. In this paper, we ha…
