Abstract:

It has been discovered that laminate composites of longitudinally magnetized magnetostrictive and transversely poled piezoelectric layers a L-T laminate composite have a giant magneto-electric ME effect under a low magnetic bias. The ME voltage coefficient is over 110 mVOe at a magnetic bias H500 Oe. This value is 5-10 times higher than that previously reported for transverse magnetized transverse polarized T-T laminates of the same layer compositions at the same bias. In this paper, we also report the magneto-elasto-electric bi-effect equivalent circuit of the L-T laminate composite and the corresponding theoretical formula of the magneto-electric voltage coefficient.
