On the dot : Large‐area nanodot arrays of Fe 2.5 Mn 0.5 O 4 (FMO; see image), with dot sizes as small as 100 nm, can be fabricated by a Mo lift‐off technique. The FMO dots grow epitaxially on the substrate and show ferromagnetic properties. Their coercive magnetic field is identical to that of continuous FMO thin film.
