  • Origins of the large piezoelectric response of samarium-doped lead magnesium niobate–lead titanate ceramics [Elektronski vir]
    Arzenšek, Matija, metalurg ...
    The recent discovery of the large piezoelectric response of Pb(Mg 1/3Nb2/3)O3- PbTiO3 (PMN-PT) ceramics inducedby samarium doping has provided a substantially improved functionality to the group of ... lead-based relaxor-ferroelectric materials. Different mechanisms have been so far proposed for the large piezoelectricity; however,the explanations are contradictory and focused on a unified description. Here, we use nonlinear harmonic piezo-electric measurements combined with multiscale structural analysis to clarify the origins of the ultrahigh piezo-electric response of samarium-doped PMN-PT. Our methodological approach allowed us to separate the multiplepiezoelectric contributions, revealing their quantitative role in the total response. The results show that the ultra-high piezoelectricity cannot be attributed to a single mechanism but is rather a complex combination of differentcontributions originating from the multiple effects of samarium doping on the long- and short-range structure ofPMN-PT. The study offers a baseline for future engineering of the key material parameters affecting the largepiezoelectric response of relaxor-ferroelectric ceramics.
