Macroscopic Room-Temperature Magnetoelectricity in Piezoelectric (Core)–Ferrimagnetic (Shell) Nanocomposites

The magnetoelectric (ME) effect, which involves the interaction of magnetic and electric fields within a material, has a significant potential for various applications. Our study addresses the limitations of conventional magnetostriction-based ME materials by demonstrating an alternative approach that achieves substantial ME effects in core-shell-type nanocomposites at room temperature. By synthesizing ferrimagnetic Fe
