Domain evolution in a magnetic metamaterial

Materials Colloquium 2020 – April, 22nd, 16:30 Zoom Sandra Skjærvø (Mesoscopic Systems) Artificial spin systems are arrays of nanomagnets that are fabricated through state-of-the-art lithography techniques. The nanomagnets interact through dipolar coupling and, depending on the arrangement of the nanomagnets, the system can…
