Artificial Spin Ice: From Correlations to Computation — •Naëmi Leo — CIC nanoGUNE BRTA, Donostia - San Sebastián, Spain — Laureate of the Hertha-Sponer-Prize 2021

Collective ordering phenomena in magnetic materials can lead to the emergence of surprising material properties, especially when spin-spin interactions are competing. Artificial spin ices, which are arrays of magnetostatically-coupled single-domain nanomagnets, have become a testbed to study emergent correlations and phase transitions in tailored two-dimensional lattices. In recent years, further functionalities of such magnetic metamaterials have been explored, based on their field-driven reconfigurability and thermally-driven relaxation behaviour. These could open up the potential for novel low-powered computation schemes.

In this talk, I will give a brief introduction into the field of artificial spin ices. Then I will discuss observation of ordering phenomena in extended lattices as well as recent developments to manipulate the relaxation kinetics via light-controlled plasmonic heating in small-scale circuits for nanomagnetic computation.
