A giant magnetoelectric (ME) effect in self-biased annealed Metglas/Pb(Zr,Ti)O-3/Metglas laminates under zero magnetic bias is reported. The remanent magnetization was increased by annealing Metglas, which generated an internal bias field. This shifted the M-H hysteresis loops, yielding large values for the ME voltage coefficient of alpha(ME) = 12 V/cm.Oe and 380 V/cm.Oe at 1 kHz and electromechanical resonance under zero magnetic bias, respectively. This self-biased laminate is shown to have a high sensitivity to ac magnetic fields. (C) 2013 American Institute of Physics. [http://dx.doi.org/10.1063/1.4794056]
