Abstract

Structural transformation between perovskite SrFeO3−δ and brownmillerite SrFeO2.5 can be induced by topotactic oxygen exchange at moderate temperatures under reducing conditions. In article number 1901984, Elías Ferreiro-Vila, Francisco Rivadulla, and co-workers show that the electric field produced by a voltage-biased AFM tip can induce such transformation at room temperature. This allows non-volatile control of the functional properties with sub-micron spatial resolution.
