New magnetic creatures discovered in artificial spin ice! We present still life, oscillators and new types of gliders. Read all about it in our latest paper "Artificial Life in-materio", hot off the press: https://direct.mit.edu/isal/proceedings/isal2025/37/66/134050 @CAL_NTNU @COMET_NTNU
Snakes in the Plane: Controllable gliders in a nanomagnetic metamaterial. Check out our latest paper about the magnetic snakes! https://www.nature.com/articles/s41467-025-62515-1 @COMET_NTNU @CAL_NTNU
In the paper, we introduce "astroid clocking" - a new method to control the dynamics of artificial spin ice, a family of nanomagnetic metamaterials. We demonstrate how astroid clocking enables ferromagnetic domains in "pinwheel" artificial spin ice to be gradually grown or reversed at will. @COMET_NTNU @CAL_NTNU
Thrilled to announce that our latest paper, "Clocked dynamics in artificial spin ice", has just been published in Nature Communications! See https://doi.org/10.1038/s41467-024-45319-7 @COMET_NTNU @CAL_NTNU
