A bottom‐up approach has been used to tune the morphology of single‐crystalline hematite from hollow spheres to nanocups. The mechanism involves the formation of nanocups through buckling of the spheres, similar to a deflated ball (see picture). As the shape changes, there is a drastic change in magnetic properties.
