INVESTIGATION OF MAGNETOELECTRIC INTERACTION IN COMPOSITE

Theoretical approach on the magnetoelectric effect in two-phase compos ite materials consisting of ferrite and piezoelectric components at va rious frequencies is developed. The mechanism responsible for the magn etoelectric effect is discussed. The generalised magnetoelectric sensi tivity tensor is calculated. The estimates of magnetoelectric sensitiv ity at low and high frequencies are given. Some experimental results o f the systems nickel-cobalt ferrite/piezoelectric ceramics of PZT-type and yttrium iron garnet/barium titanate are presented. The brief revi ew of the previous work is given.
