Multiple energy-scales in vertex-frustrated mesospin systems
Henry Stopfel, Unnar B. Arnalds, Aaron Stein +3
The interplay between topology and energy-hierarchy plays a vital role in the collective magnetic order in artificial ferroic systems. Here we investigate, experimentally, the effe…
Collective magnetic dynamics in artificial spin ice probed by AC susceptibility
Merlin Pohlit, Giuseppe Muscas, Ioan-Augustin Chioar +8
We report on the study of the thermal dynamics of square artificial spin ice, probed by means of temperature and frequency dependent AC susceptibility. Pronounced influence of the…
Observation of the nonlinear Wood's anomaly on periodic arrays of nickel nanodimers
Ngoc-Minh Tran, Ioan-Augustin Chioar, Aaron Stein +6
Linear and nonlinear magneto-photonic properties of periodic arrays of nickel nanodimers are governed by the interplay of the (local) optical response of individual nanoparticles a…
The importance of the weak: Interaction modifiers in artificial spin ices
Erik Östman, Henry Stopfel, Ioan-Augustin Chioar +4
The modification of geometry and interactions in two-dimensional magnetic nanosystems has enabled a range of studies addressing the magnetic order, collective low-energy dynamics,…
Disorder strength and field-driven ground state domain formation in artificial spin ice: experiment, simulation and theory
Zoe Budrikis, J. P. Morgan, J. Akerman +5
Quenched disorder affects how non-equilibrium systems respond to driving. In the context of artificial spin ice, an athermal system comprised of geometrically frustrated classical…
A Virtual Young's Double Slit Experiment for Hard X-ray Photons
A. F. Isakovic, A. Stein, J. B. Warren +7
We have implemented a virtual Young's double slit experiment for hard X-ray photons with micro-fabricated bi-prisms. We observe fringe patterns with a scintillator, and quantify in…
