Article published on an artificial 2D XY spin system
Using a combination of low-energy muon spin relaxation and resonant x-ray scattering, we showed that an ensemble of nanoscale magnetic disks, mimicking freely-rotating macrospins, displays a phase transition into an ordered state
This offers new degrees of freedom for the study of artificial spin systems. external page N. Leo et al., Nature Communications 9, 2850 (2018) external page PSI Scientific Highlights
