Ab Initio indications for giant magnetoelectric effects driven by structural softness.
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 BiFeO(3) thin films.
