| Abstract: | In this paper,a L-T model of layered magnetoelectric composite materials is presented,which,based on piezoelectric effect and piezomagnetic effect constitutive equation,using the method of equivalent scheme,is used to analyze the magneto-ionic voltage coefficient of the composite materials,and to obtain various relations among physical parameters of the composite materials. Then a numerical computation is made of the materials magnetoelectricity response,and results are compared with those of interrelated f... |
