Piezoelectric Characterization of (0.6)BiFeO^sub 3^-(0.4)PbTiO^sub 3^ Multiferroic Ceramics
In this work, the full piezoelectric characterization of high-energy ball-milled (HEBM) (0.6)BiFeO...-(0.4)PbTiO... (HE-BF PT60/40) multiferroic magnetoelectric ceramics was performed. The whole set of piezoelectric, mechanical, and elastic coefficients was obtained. The results revealed piezoelectr...

description | In this work, the full piezoelectric characterization of high-energy ball-milled (HEBM) (0.6)BiFeO...-(0.4)PbTiO... (HE-BF PT60/40) multiferroic magnetoelectric ceramics was performed. The whole set of piezoelectric, mechanical, and elastic coefficients was obtained. The results revealed piezoelectric coefficients, namely d31=-41.6 x 10... m/V and g...=-9.65 x 10... Vm/N (at room temperature), as high as those of other commercial piezoceramics. In fact, HE-BFPT60/40 piezoceramics produced by HEBM showed three times higher piezoelectric coefficients than those previously reported for conventionally synthesized piezoceramics. The thermal stability of d... and g... piezoelectric coefficients near room temperature, as well as the weak ferromagnetic response of HE-BFPT60/40 samples, make the (0.6)BiFeO...-(0.4)PbTiO... multiferroic magnetoelectric ceramics potential candidates for applications in future multifunctional piezo-magnetic-electric devices.
