Phys. Rev. Lett. 105, 037208 (2010) [4 pages]Ab Initio Indications for Giant Magnetoelectric Effects Driven by Structural SoftnessReceived 19 April 2010; published 16 July 2010 We show that inducing structural softness in regular magnetoelectric (ME) multiferroics—i.e., tuning the materials to make their structure strongly reactive to applied fields—makes it possible to obtain very large ME effects. We present illustrative first-principles results for BiFeO3 thin films. © 2010 The American Physical Society URL:
