Electric Control of Magnetization and Interplay between Orbital Ordering and Ferroelectricity in a Multiferroic Metal–Organic Framework

Abstract

Forget me not: In a new multiferroic metal–organic framework (see structure, Cu green, O red, C black, N blue, H gray; arrows show spin configuration), Jahn–Teller and antiferro-distortions induce a switchable ferroelectric polarization, which is coupled to a weak ferromagnetic component. This true magnetoelectric multiferroic should be very attractive for advanced memory devices.
