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 / at very low fields ( kOe) near TC in multiferroic Bi2NiMnO6 thin film. More importantly, the insensitivity of to temperature and frequency variations, and pronounced change in near TC in zero magnetic field attribute the observed large MDE to the inherent exchange magnetoelectric interactions.
