Co-existing magnetization reversal mechanisms in shakti spin ice systems
Vladyslav M. Kuchkin, Unnar B. Arnalds, Hannes Jónsson +1
The switching mechanisms in artificial spin ice systems are investigated with focus on shakti and modified shakti lattices. Minimum energy paths are calculated using the geodesic n…
Magnetic texture control in ion-implanted metamaterials
Christina Vantaraki, Kristina Ignatova, Dmitrii Moldarev +5
We study experimentally the impact of the additive fabrication method on the magnetic properties of Fe-implanted Pd square artificial spin ice lattices. Our findings show that…
Magnetic Order and Long-Range Interactions in Mesoscopic Ising Chains
Christina Vantaraki, Matías P. Grassi, Kristina Ignatova +4
We investigate the design of magnetic ordering in one-dimensional mesoscopic magnetic Ising chains by modulating long-range interactions. These interactions are affected by geometr…
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…
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,…
A new look on the two-dimensional Ising model: thermal artificial spins
Unnar B. Arnalds, Jonathan Chico, Henry Stopfel +7
We present a direct experimental investigation of the thermal ordering in an artificial analogue of an asymmetric two dimensional Ising system composed of a rectangular array of na…
