Abstract

Single-phase multiferroics exhibiting a large low-field magnetodielectric effect (MDE) are of great interest for the practical realization of multifunctional devices, as existing multiferroics demand large magnetic fields to cause any significant MDE. Here, we report remarkably large MDE equivalent to Delta epsilon '/epsilon ' similar to 6% at very low fields (H <= 5 kOe) near T-C in multiferroic Bi2NiMnO6 thin film. More importantly, the insensitivity of epsilon' to temperature and frequency variations, and pronounced change in epsilon ' near T-C in zero magnetic field attribute the observed large MDE to the inherent exchange magnetoelectric interactions.
