N2 - Microstructural, piezoelectric, dielectric, and magnetoelectric properties of laminated trilayer sintered magnetoelectric (ME) composite was analyzed. Powders of lead compounds (0.9 PZT-0.1PZN) and Ni0.6Cu 0.2Zn0.2Fe2O4 (NCZF) were synthesized using conventional mixed oxide method. Microstructural analysis of the sintered samples was done by a Zeiss Leo Smart Scanning Electron Microscopy (SEM) using polished and thermally etched samples. Dielectric constant measurements were performed using a HP 4284 LCR meter, and the ME voltage coefficient by a lock-in amplifier method. Experimental investigation showed that the piezoelectric phase had grain size of more than 1μmeter, while magnetoresistive phase had grain size of 3-5 μm. The observed ME coefficient can be further enhanced by reducing the macrodefects and optimization of ferrite to PZT thickness.
