Nanomagnet shape effects on magnetic reversal in artificial spin ice

This dataset contains micromagnetic simulation results exploring how the shape of elongated nanomagnets influences magnetic reversal processes in artificial spin ice. By systematically varying the island geometry from rectangular to elliptical shapes, the simulations reveal how deviations from idealized coherent rotation emerge due to curling and pinning of the magnetization at the island edges. Furthermore, increasing inter-island interactions leads to a more complex interplay between internal magnetization dynamics and external coupling effects. These results provide insight into the role of shape anisotropy in artificial spin ice and offer a foundation for designing nanomagnetic systems with tailored reversal properties.
