Structural phase transitions driven by oxygen vacancy ordering can drastically affect the properties of transition metal oxides. S. van Dijken, L. D. Yao, and co-workers demonstrate on page 2789 that the focused electron beam of a transmission electron microscope can be used to control structural phase transitions in epitaxial La2/3Sr1/3MnO3. The image is an artistic impression of the experiments. It consists of two scanning transmission electron microscopy images, one before and one after electron-beam irradiation, which are blended to illustrate the writing of a new structural phase in the area that is exposed to the electron beam.
