Abstract

Abstract : A one‐dimensional tetrahedral chain network in a brownmillerite structure gives rise to a coupled ferroelectric and ferromagnetic behavior. In article number1808104, Woo Seok Choi and co‐workers describe the discovery of a room‐temperature ferroelectric ferromagnet in a SrFeO2.5 epitaxial thin film, which exhibits an unconventional combined polar distortion with the mechanism of the coupled ferro‐orderings.
