摘要：

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. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
