Grain boundaries of strontium‐doped lanthanum manganite thin films are characterized by Albert Tarancón and co‐workers in article number 1805360 , by a strong modification of both the anionic and cationic composition. The grain‐boundary local nonstoichiometry can be altered by tuning the overall cationic content in the thin films, offering a tool to engineer the electronic and oxygen mass‐transport properties of these interfaces.
