Abstract

A simple model of the magnetoelectric (ME) effect in cylindrical layered composites is presented. The cylinder is replaced by the effective layered plate structure with effective length, Leff, thickness t and height h. In the axial coupling mode, the effective magnetic field acts along the length direction (Leff). However, in the vertical coupling mode, the effective magnetic fields act in two directions simultaneously, one along the thickness direction (normal, t) and the other along the effective height (tangential, Leff) direction, respectively. Experimental results and theoretical analysis indicated that the cylindrical layered composites ME voltage coefficient is much higher compared with that of the layered plate.
