Abstract

This study reports the low frequency magnetoelectric (ME) response of the sintered composites comprising of a piezoelectric phase Pb (Zr0.52 Ti0.48) O3 (PZT) and magnetostrictive phases Ni Fe1.9 Mn0.1 O4 (NFM) and Ni0.8 Zn0.2 Fe2 O4 (NZF) with varying ferrite contents of 3, 5, 10, 15, and 20 mol %. It was found that the ME coefficient for the PZT-NZF samples shows considerably less scattering as a function of frequency and the composition 0.8PZT-0.2NZF exhibited a flat response in the range of 10-100 Hz with a magnitude of 220 mVcm Oe. This composition was used to design the magnetic field anomaly detector mounted in front of a global positioning system (GPS) controlled vehicle. The results from the vehicle test clearly demonstrate the feasibility of using sintered ME composites for magnetic field detection in the noisy environment.
