Incipient ferroelectricity

WebThe microwave dielectric resonance properties of Na1/2Bi1/2Cu2.82Mn0.18Ti4O12 (NBCMTO) ceramics are reported. Single-phase NBCMTO powder were obtained from the mixed oxide route at 975°C and dense ceramics (~ 97% of the theoretical X-ray density) with a grain size distribution between ~ 2 and 10 μm by sintering in air at 1060°C. Ceramics … WebFeb 15, 2024 · Here, we studied this phonon via polarization-dependent terahertz spectroscopy. We observed softening of this mode with decreasing temperature, indicative of incipient ferroelectricity, which we explain through a model including strong anharmonicity with a quartic displacement term.
