Multiferroic Materials: A Room‐Temperature Ferroelectric Ferromagnet in a 1D Tetrahedral Chain Network (Adv. Mater. 24/2019)

A one‐dimensional tetrahedral chain network in a brownmillerite structure gives rise to a coupled ferroelectric and ferromagnetic behavior. In article number 1808104, Woo Seok Choi and co‐workers describe the discovery of a room‐temperature ferroelectric ferromagnet in a SrFeO2.5 epitaxial thin film...

Zusammenfassung:	A one‐dimensional tetrahedral chain network in a brownmillerite structure gives rise to a coupled ferroelectric and ferromagnetic behavior. In article number 1808104, 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.
