Regular arrays of magnetic perovskite dots less than 100 nm in diameter (see Figure) are made by a process incorporating pulsed laser deposition, patterning with electron-beam lithography, and exposure to neutralized 200 eV Ar ions. The nanodots preserve the magnetic properties of large-area magnetic perovskite films, and are the smallest structures made of these materials to date.
