Abstract
The great magnetoelectric(ME) effect is a product property of the composite consisting of individual piezoelectric and magnetostrictive phases. The TbDyFe/PZT laminate composites were prepared by magnetron sputtering, and the ME coefficients αE were examined experimentally and calculated by using a finite e lement analysis software. Results showed that the experimental data were in agreement with the calculated results and the value of αE reached the maxim um at the resonance frequency, and αE increased with the increase of the magnetostricive thickness.
