Ionic conductivity transitions in antiperovskite ionic conductors
… with high ionic conductivity, including octahedral tilt disordering, paddlewheel mechanism and double paddlewheel mechanism. Carrying out temperature-dependent synchrotron XRay diffraction, differential scanning calorimetry, impedance spectroscopy, neutron diffraction, nuclear magnetic …

New perspectives of pure and lanthanum modified lead zirconate titanate crystalline solutions
Two types of oxygen octahedral rotational systems (R- and M-type) were found in the rhombohedral phase field of lead zirconate titanate (PZT). A hierarchy of domain structure was observed in the high temperature rhombohedral ferroelectric (FE) state, where local octahedral tilt domains on the scale …

Exploring the connections between nanostructure and operational stability in next-generation energy materials
… that the composition impacts the degree of octahedral tilt, which is essential to restricting the transition to hexagonal phase impurities. Additionally, it is demonstrated that while a judicious mix of A-site cations can be used to stabilise the photoactive black phase of halide …

Structure-property correlations in compositionally complex ferroelectrics
… types of heterogeneities: chemical order, oxygen octahedral tilt order, and oxygen octahedral distortion order. These heterogeneities vary with Ti content and show spatial correlation with lowangle domain walls, indicating their role in breaking down the long-range polar order and stabilizing the …
