Magnetoelectric (ME) effect has been studied in a structure of a magnetostrictive TbFe{sub 2} alloy, two piezoelectric Pb(Zr,Ti)O{sub 3} (PZT) ceramics, and two nonmagnetic flakes. The ME coupling originates from the magnetic-mechanical-electric transform of the magnetostrictive effect in TbFe{sub 2} and the piezoelectric effect in PZT by end bonding, instead of interface bonding. Large ME coefficients of 10.5 and 9.9 V cm{sup -1} Oe{sup -1} were obtained at the first planar acoustic and third bending resonance frequencies, which are larger than that of conventional layered TbFe{sub 2}/PZT composites. The results show that the large ME coupling can be achieved without interface coupling.
