North-West- or South-East-Coupling

Caption

If a group of cobalt atoms aligns to the North or South (red), the neighbouring cobalt atoms align to the West or East (blue). The orientation of the neighbouring atoms is within the plane. This interaction requires sandwiching of the cobalt layer between a platinum layer (below, beige) and an aluminium oxide layer (above, not shown here).
