Significantly Enhanced Structural, Dielectric and Impedance Properties of BCZT-BFO Sensors

Multiferroics like [(Ba0.85Ca0.15) (Zr0.1Ti0.9) O3, BCZT] and (BiFeO3, BFO) with stochiometric amount were prepared mixed oxide solid state route adding CuO. The compositions were confirmed by X-ray diffraction technique, FTIR confirmed the formation of bonds and the clear idea of bonding pairs, FESEM supported the results of microstructure, and it was revealed that the addition of CuO increased the densification while it was also served as a sintering agent. The impedance spectroscopy (IS) was the tool that explain the relaxation phenomenon of the composition making agreements with the conduction mechanism that the material can be used as negative temperature coefficient of resistance (NTCR) for the applications of capacitors, sensors, actuators, and energy devices.
