Abstract
Abstract: The magnetoelectric characteristics on layered Ni-PZT-Ni , Co, Fe composites by epoxy bonding for magnetic field sensor were investigated in the low-frequency range. The ME coefficient of Ni-PZT-Ni, Ni-PZT-Co and Ni-PZT-Fe composites reaches a maximum of 200 mV / cm·Oe at H dc =110 Oe , 106 mV/cm·Oe at H dc =90 Oe and 87 mV/cm·Oe at H dc =160 Oe , respectively. A trend of ME charateristics on Ni-PZT-Co , Ni-PZT-Fe composites was similar to that of Ni-PZT-Ni composites . The ME output voltage shows linearly proportional to ac field H ac and is about 0∼150 mV at H ac =0∼7 Oe and f =110 Hz in the typical Ni-PZT-Ni sample. The frequency shift effect due to the load resistance R L shows that the frequency range for magnetic field sensor application can be modulated with appropriate load resistance R L . This sample will allow for a low-magnetic ac field sensor in the low-frequency (near f =110 Hz ).
