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 ≡ δϵ /ϵ∼ 6% at very low fields (H ≤ 5 kOe) near TC in multiferroic Bi₂NiMnO₆ thin film. More importantly, the insensitivity of ϵ to temperature and frequency variations, and pronounced change in ϵ near T_C in zero magnetic field attribute the observed large MDE to the inherent exchange magnetoelectric interactions.
