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…
Tuning metal-insulator transitions in epitaxial VO thin films
Einar B. Thorsteinsson, Seyedmohammad Shayestehaminzadeh, Unnar B. Arnalds
We present a study of the synthesis of epitaxial VO films on -plane AlO substrates by reactive dc-magnetron sputtering. The results reveal a temperature window,…
Magnetic order and energy-scale hierarchy in artificial spin ice
Henry Stopfel, Erik Östman, Ioan-Augustin Chioar +6
In order to explain and predict the properties of many physical systems, it is essential to understand the interplay of different energy-scales. Here we present investigations of t…
