Investigation of magnetoelectric interaction in composite

Theoretical approach on the magnetoelectric effect in two-phase composite materials consisting of ferrite and piezoelectric components at various frequencies is developed. The mechanism responsible for the magnetoelectric effect is discussed. The generalised magnetoelectric sensitivity tensor is calculated. The estimates of magnetoelectric sensitivity at low and high frequencies are given. Some experimental results of the systems nickel-cobalt ferrite/piezoelectric ceramics of PZT-type and yttrium iron garnet/barium titanate are presented. The brief review of the previous work is given.
