The magnetostrictive and magnetoelectric (ME) properties of laminate composites of Fe-20 at. % Ga and Pb(Zr,Ti)O-3 (PZT) have been studied for laminates of different geometries. The results show that (i) a long-type magnetostrictive Fe-20 at. % Ga crystal plate oriented along (001), and magnetized in its longitudinal (or length) direction has higher magnetostriction than a disk-type one; and consequently (ii) a long-type Fe-20 at. % Ga/PZT laminate has a giant ME effect, and is sensitive to low-level magnetic fields.
