Geometrical frustration arises when not all interactions are simultaneously satisfied, and artificial spin systems offer an ideal platform to study this with the use of microscopy techniques [1, 2]. Using spatially resolved x-ray photoemission electron microscopy (X-PEEM), we compare the thermal relaxation in artificial square spin ice fabricated out of Permalloy films, which were grown on a...
