A Pb(Zr,Ti)O3-bimorph/NdFeB laminate device has a giant magnetoelectric (ME) effect. Our results reveal a giant ME coefficient of 16V∕cmOe or 62nC∕cmOe at a low (subresonant) frequency of 10Hz, and one of 250V∕cmOe or 960nC∕cmOe at a first order resonant bending mode frequency of ∼60Hz. The findings show a simple means by which to achieve magnetoelectric effects, without the use of magnetostrictive material.
