Abstract: The magnetoelectric (ME) response and magnetic-field sensitivities of engineered laminate sensors comprised of magnetostrictive and piezoelectric phases are compared. The studies have resulted in the enhancement in the magnetic-field sensitivity for the structures with single crystals and the noise floors are lower for composites with Pb([Mn.sub.1/3][Nb.sub.2/3])[O.sub.3]-PbTi[O.sub.3] (PMN-PT) or Pb([Zn.sub.1/3][Nb.sub.2/3])[O.sub.3]-PbTi[O.sub.3] (PZN-PT) fibers than those with Pb(Zr,Ti)[O.sub.3] (PZT).
