Enhancement of magnetoelectric effect in multiferroic fibrous nanocomposites via size-dependent material properties

We investigate the effective material properties of a multiferroic fibrous nanocomposite with size effects along its interface. The closed-form expression of the effective moduli of the nanocomposite shows that its response with interface effects depends on the size of the embedded fibers in the composite, a phenomenon different from the result based on the classical theory. We further demonstrate that the magnetoelectric effect can be substantially enhanced via proper design of the interface, providing an alternative avenue for controlling and, in particularly, increasing the magnetoelectric effect.
