Geometry Dependence of Emergent Magnetisation Dynamics in Interconnected Nanomagnets

Abstract: Six days of OFFSPEC beam time is requested to expand our recent investigations of emergent magnetisation dynamics in ensembles of interconnected ring-shaped nanowires. In recent polarised neutron reflectivity (PNR) studies at OFFSPEC we showed that when these ensembles are subjected to rotating magnetic fields they host dynamic populations of domain walls, the equilibrium number of which develops emergently from the nature of domain wall interactions at ring junctions, which we control with the strength of the applied field. Here, we propose to explore these behaviours in arrays with differing symmetry and size to gain understanding of how the rings’ connectivity affects the emergent dynamics of the array as a whole
