Abstract
The lead magnesium niobate (PMN; PbMg1/3Nb2/3O3) and bismuth ferrite (BFO; BiFeO3) electronic compound has been fabricated and its excitation through electric field has been experimentally investigated. The unveiled excellent material properties like frequency independent and temperature dependent high dielectric constant and low dielectric loss substantiate the relaxor behavior of the processed material. A parallel plate capacitor structure is designed in order to reveal the material’s excitation through the generated internal electric field which has also been affirmed. The experimental results exhibit the dependence of excitation intensity on the material properties, driving frequency, relative position and generated electric field strength. The intensity of excitation attains its peak when the driving frequency is synchronized with the mechanical resonant frequency of the fabricated relaxor dielectric component.
