Real-space observation of magnetic excitation in quasicrystal lattices

Magnetic reversal mechanism of quasicrystal artificial spin ice were studied with in-situ TEM magnetizing experiments. Using this technique, a team from Argonne National Lab found a new dendritic magnetic reversal mechanism in the quasicrystal spin ice lattitces. “As fabricated” and “Demagnetized” schematics show examples of the groups of magnetic bars whose magnetization reversed at each of the two field values.
