摘要：This paper develops a self-biased magnetoelectric (ME) composite Metglas/H-type-FeNi/PZT (MHFP) of H-type magnetization-graded Metglas/H-type-FeNi fork and piezoelectric Pb(Zr,Ti)O-3 (PZT) plate. By using the magnetization-graded magnetostrictive layer and symmetrical H-type structure, giant self-biased ME coupling and multi-peak phenomenon are observed. The zero-biased ME voltage coefficient of MHFP composite reaches similar to 63.8V/cm Oe, which is similar to 37.5 times higher than that of traditional FeNi/PZT laminate. The output ME voltage has a good near linear relation with H-ac and is determined to be similar to 5.1V/Oe and similar to 10.6mV/Oe at similar to 65 kHz and 1 kHz, respectively. These indicate that the proposed composite show promising applications for ME transducers and high-sensitivity self-biased magnetic sensors. (C) 2015 AIP Publishing LLC.
