摘要：

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.
