Highly attractive : Features typical of a single‐molecule magnet (that is, a high anisotropy barrier of 25 K, very slow zero‐field relaxation, and a large coercive field of 15 kOe) are exhibited by a Dy III Cu II nonanuclear complex, which was synthesized by using a Schiff base ligand. The picture shows the {DyCuO} core of the cluster (dark green Dy, light green Cu, red O) and low‐temperature magnetization curves.
