Abstract
Nanocomposites consisting of 2 dimensional (2D) amorphous Cr2O3-CoFe2O4 and crystalline 2D Cr2O3-CoFe2O4 were prepared and the room temperature magnetoelectric coupling was studied. This study also investigated the effect of crystalline 2D Cr2O3 on the exchange bias induced magnetoelectric coupling in the composites. Evidence for the exchange bias in the composites is obtained from field cooling - zero field cooling (FC-ZFC) measurements. The 2D crystalline Cr2O3 composite exhibits high magnetoelectric coupling coefficient at room temperature when compared to bulk composite for the corresponding Cr2O3. These composites augurs well for applications especially for energy harvesting and spintronics.
